Different ways to shutdown your pc

There are so many different ways to turn off your Windows XP computer, let's look at some of them:


1. The standard approach - click the Start Button with your mouse, then select the Turn Off menu and finally click the Turn Off icon on the Turn Off computer dialog. blink.gif

2. Press Ctrl+Esc key or the Win key and press u two times - the fastest approach.

3. Get the Shutdown utility from Download.com - it add the shut down shortcuts for you. Else create them yourself using approach 4.

4. Create a shutdown shortcut on your desktop. Right click on the desktop, choose New Shortcut and type shutdown -s -t 00 in the area where you are asked to specify the location of the program file. Now you can just double click this icon to turn off the computer. The best location would be your quick launch bar.

Using Task ForceQuit Pro to Quickly End Tasks - Easy way







After some digging around in the registry, I have traced the problem to the fact it writes a registry entry when you tick the box, but the next time it checks if the box has been ticked before, a different non existent registry key is checked. Below are the registry entries that will stop the activation window appearing and also stop the success window from popping up again. Copy the text below into a notepad text file, and save as ‘yourname.reg’. Then double click the file to import into the registry. Works on current version 1.0.2.0.
Windows Registry Editor Version 5.00

If Task ForceQuit Pro didn’t have these nagging screen issues and the restart / shutdown buttons could be made a bit safer, it has the potential to be a very good little utility. With the registry entries above applied, it still makes a handy tool even though you have to take care with the bottom row of buttons.Compatible with Windows 7, Vista and XP

The steps to Get GPS Navigation on My Smartphone ?

 You can use your smartphone to get GPS navigation complete with satellite tracking to help you on important trips. Mobile GPS is offered by a variety of vendors giving you the option to choose the service with amenities that best suit you. In order to take advantage of GPS services on your smartphone, you must have a data plan with your service provider. Advanced GPS programs are available for a fee, but many free applications also exist.


Browse the main menu on your smartphone for the icon labeled "Applications." Click this icon.



Type "GPS" into the search bar. A list of GPS applications will appear. Some may require a subscription to the service in addition to a fee to download. However, you can also find a "Maps" application that offers directions as a feature rather than the main function of the program. These applications are typically free and allow you to identify your position on the map using satellite technology.


Click "Download" then "OK" when prompted. Once the application download is complete, the GPS program will be added to the desktop of your smart phone. Set up your GPS by entering your current location and a list of favorites under the "Settings" menu of your new application.

The Shut Down Comparison among Windows XP,Windows Vista and Ubuntu 9.04

Studying the ways of shutting down the computer has been kind of a research area among operating system GUI designers. Although we as users do not see it, designing a simple interface like shutting down the computer takes lots of user studies and research. Today with number of operating systems that we use, we can see different approaches they have taken on how to present the user with the least annoying Shut Down interface.

I'll compare the shut down mechanisms of the 3 major operating systems we use; Windows XP, Windows Vista and Ubuntu 9.04. Specifically, I'll consider the number of mouse clicks and mouse movement they require from the user. Although there are shortcut keys associated with them, I won't consider them since ordinary users won't know about them anyway.



Windows XP

In XP, users have to go through 2 dialog boxes to accomplish the task. First, the start menu and the second, the final shut down box.

  1. Click Start button. (click 1) 
  2. Click "Turn Off Computer". (click 2) 
  3. Move the mouse to the center of the screen. 
  4. Click "Turn Off" button. (click 3)



    It is clear that this involves 3 mouse clicks and a mouse movement across the screen. Although, as IT people the mouse is in our "genes", this is a fair amount of work load for a typical user. (You should've seen the time it takes for our grandma to do this)


    Windows Vista
    This is totally confusing for new users. There are number of ways you can shut down. With the default settings, you see a yellow "shut-down-like" button. People mistake this as the shut down button where it actually means "Sleep". To truly shut down the computer, you have to click the small arrow, and choose Shut Down from the not-so-simple menu that appears. This process needs a very high amount of concentration from the user.

    This is the way you do it with default settings.

    1. Click Start button. (click 1) 
    2. Click the small arrow to the right of Sleep and Lock buttons. (click 2) 
    3. Choose "Shut Down" from the the list. (click 3) (This list has 6 items. If you needed to Restart you have to find where restart is in the list. Shut Down is easier since it's the bottom-most item.) 



    This process requires 3 clicks (same as XP). But it also requires the user to thoroughly concentrate on what he/she is doing, which is too much to ask from an ordinary user.

    You can change the behavior of the Sleep button to Shut Down via power settings. Read this for instructions on how to change it. Then the whole process changes.

    1. Click start button. (click 1) 
    2. Click "Shut Down" button. (click 2) 



    Now it's only 2 clicks. So simple. The catch is that the red Shut Down button is very easily reachable. User don't get any confirmation dialog box after clicking this. So when you click it, wooosh! it's bye bye windows. So it's prone to unintended shut downs.

    In Vista they have increased the number of ways to shut down and none of them are perfect. XP way is better in my opinion.


    Ubuntu 9.04

    Ubuntu 9.04 reportedly have a nice and clean interface. This is true for their Shut Down mechanism too. Although they have borrowed the idea fromApple MacOS X, they does a good job integrating it with their user interface.

    1. Click the power button at the upper-right corner. (click 1) 
    2. Choose Shut Down from the menu. (click 2) (Menu has 6 items. Shut Down is at the bottom and Restart is the one before that) 

    That's it. If you are lazy you can leave your computer and it will shut down. But if you made an error in your decision you can always cancel it since it displays this time-out dialog box.




    If you choose, you can continue the previous process further.

    1. Move the mouse to the Shut Down dialog box. 
    2. Click the shut down button. (click 3) 
    See how thoughtful they have been. The computer will shut down without any user interaction within 60 seconds. If you are in a hurry, you make an extra mouse click on the Shut Down button on the time-out dialog.

    It's "2 clicks" or "3 clicks with a mouse move" depending on the way you choose. But always the result is the same and you have the confirmation dialog so you can undo your decision. This is the nicest shut down process I've seen so far (including MacOS X).

    Finally, see how much we can talk about a simple operation like this. (as if we don't have anything else to do!) These subtle changes effect the user's perception of an operating system. And most of the time, these are the "only" things that a user uses to judge an operating syste

    Performance Monitoring in Windows Vista

    Most of us like to hate Vista! But with enough system resources and good device drivers, Vista can deliver a really smooth user experience. In addition to having a fancy UI, Vista includes some very powerful tools that system administrators can use to monitor system activity. These tools will help you to dig into system programs and startup lists and fine tune your system performance.

    Windows Defender: Software Explorer

    Windows Defender is a crappy tool which comes with windows to detect malicious programs. Due to its uselessness I have turned it off. But Defender has a tool called Software Explorer which is way better than using "msconfig" and "Task manager" to monitor running processes.

    Go to Control Panel -> Programs -> Windows Defender -> Tools ->Software Explorer

    Startup Programs

    This gives a more clear and detailed view than "msconfig" tool. Since it has the ability to group Manufacturer wise, you can clearly focus on those no-name entries which could most probably be viruses.

    Network Connected programs

    This shows a complete list of programs has network connectivity. To view detailed information about network communication, you can use theReliability and Performance Monitor.


    Performance Information and Tools

    Go to Control Panel -> System and Maintenance -> Performance Information and Tools -> Advanced Tools (on the left pane)

    These include some tools which give detailed performance information reports.

    Reliability and Performance Monitor

    Click "Open Reliability and Performance Monitor" in Advanced performance tools.


    Network monitor showing connections made by uTorrent

    This is one-stop place to monitor detailed system wide activity. You can monitor Network activity, Memory activity, Disk usage activity and so on. One interesting feature is that you can see details about all the open files and their disk access at any given time.


    Files opened by every process and their read/write activity


    System Stability Chart

    Windows collects system statistics over time and keeps a history of events in the event log. Vista includes a chart feature which draws a chart over time which varies due to system changes.

    Go to "Reliability Monitor" in the left pane.


    Bootup performance monitoring in Event log

    Event log includes detailed statics for application and services startup times (including Windows boot time) so you can identify which applications delays windows startup. Windows automatically notifies you if a certain application has taken an unusual amount of time to start.

    Click "View performance details in the Event log" in Advanced performance tools.

    Ok that's the lot. Using these tools you can administer your system to identify any unwanted activity. And with better hardware resources and drivers, I think Vista is a better OS than XP. User experience wise and system administration wise.

    How To Install Windows 8 On A Windows 7 Tablet ? - Simple Guide

    If you have a tablet capable of running the Windows 7 operating system, then you might be interested in trying out a more tablet-oriented Windows OS, i.e., Windows 8. Although the currently available Windows 8 build is still in its pre-beta stage, however, you might find the new Metro UI to be more suitable for your tablet. In this post, we will provide you with a guide for installing Windows 8 on a Windows 7 tablet.




    Disclaimer: Despite the fact that many Windows 7 PCs and tablets are capable of running Windows 8 Developer’s preview, it must be noted that installing Windows 8 on your tablet can result in issues. Please follow this guide at your own risk. 

    Requirements:
    • Windows 8 ISO
    • Bootable Windows 8 USB. 
    • At least 20GB of free hard disk space (recommended)

    1. Windows 8 installation from USB

    Instructions:
    • Connect and boot your Windows 7 tablet from the bootable USB. To do this, you may have to change your BIOS settings.
    • Once the tablet boots from USB drive, follow the regular installation procedure to install Windows 8 on your tablet.
    • After the installation is complete, install the respective drivers (which can be downloaded from your manufacturers website).

    2. Windows 8 Installation From ISO

    Using this method, you can install Windows 8 on a tablet by mounting the Windows 8 ISO to a disc mounting application, and initiating the installation from the .EXE file.

    Instructions:
    • Login to a regular Windows 7 session on your tablet, and make sure that you have a system backup.
    • Mount the Windows 8 ISO image with a disc mounting tool. You can pick a free disc mounting application from our compilation of the 20 best disc mounting applications.
    • Now, open the virtual disc drive and run the EXE file to proceed with the Windows 8 installation. During installation, select the Windows 7 drive to overwrite Windows 7 with Windows 8. Your Windows 7 data will be moved to the Windows old folder after the installation of Windows 8.


    Although Windows 8 can be uninstalled , we recommend you to keep a backup of your Windows 7 installation to revert the changes.

    How To Solve Laptop From Overheating [Windows 7]?

    A few months back, I bought a new Core i3 laptop, hoping to run more resource intensive applications and games with better performance. While most of the applications seem to run without any issues, I have been dealing with a few thermal heating issues while playing games or running encoding tasks. For some odd reason, even reducing the affinity of the application or the game, does not eliminate the heating problem. I even bought a cooling pad, and tried switching to lower graphic options, but that, too, has resulted in minimum heat reduction. After going through many methods of reducing system heat up, it appears that there is only one true method that may be more effective than others (courtesy of our former editor, Ghaus Iftikhar), i.e., to reduce the maximum processor state from the laptop’s power settings. In this post, we will tell you how to prevent your system from heating up by adjusting the power options for your processor state.

    This tip might come in handy not just for gamers and people who wish to run resource intensive application in the wake of overheating laptops, but also if, for some reason, you are unable to return a laptop with a heating issues (perhaps due to warranty constraints), or are dealing with an old laptop, which won’t take the brunt any more.

    Before explaining the method of reducing the maximum processor state, let us take a look at the logic behind reducing the maximum processor state to prevent overheating of your laptop. Reducing the maximum processor state for your laptop (both when it is on battery or when the power cable is plugged in), reduces the processor’s performance a notch (depending on your settings) and prevents it from being used at optimum potential by an application or game, which will reduce thermal heating. For example, if you are playing a game that is consuming 100% of your processor’s capacity, then it may also result in heating up your system, whereas reducing the battery power state to, say 80%, can resolve this problem, and also result in battery power conservation.

    To change these settings, go to Power Options from the Control Panel or the system tray menu.




    Now go to Change Plan Settings –> Change Advanced Power Settings.



    In the new window that pops-up, expand Processor Power management –> Maximum processor state, and reduce the on battery and plugged in power settings. The settings you keep will depend on your preferences and the capability of your system.

    Based on our experience, we have noticed that that the laptop overheats when the processor is running at 100% processor state. Reducing the processor state by a few notches results in the reduction of temperate by 10-20 C, which results in a minor performance dip. We used Speccy to check for temperate during testing, based on which the processor running on 95% processor state gave the same performance (barely noticeable dip), with a drop of 10-20 C. You can keep an even lower processor state (such as 80-85%) to make sure that your laptop heats up even less.


    The above mentioned tip should easily prevent your laptop from heating up; however, make sure that the processor state is not reduced very low in order to prevent reducing your processor’s performance to an undesirably low level.

    How to create a Windows Restore Point?

    A restore point can be created automatically or manually, depending on the actions of the user. Windows will create a restore point automatically when the user installs Windows for the first time on a computer and when Windows updates are installed. This is done in the event there are problems sometime after Windows or updates were installed and the user needs to rollback Windows to that previous installation/restore point. Below are the steps for how to create a restore point manually at any time.


    Windows Vista and Windows 7 users
    To create a restore point in Windows Vista and Windows 7, follow the below steps.

    1. On the Windows desktop, click START, find Computer (or My Computer) in the Start Menu, right-click with your mouse and select Properties.


    2. A new window will open. On the left side, click on the System protection option. This will open the System Properties window, with the System Protection tab selected. (If the System Protection tab is not selected, click on that tab to select it.)

    3. Near the bottom on the System Protection tab, click the Create button.


    4. Another small window will open. Enter a description for the restore point in the text field and click the Create button.


    The restore point will be created and available to rollback to if ever needed.

    If you ever need to rollback Windows Vista or Windows 7 to an earlier time, on the System Protection tab, click the System Restore button and follow the prompts to select a restore point and initiate the rollback.

    Windows XP users

    To create a restore point in Windows XP, follow the below steps.

    1. Click Start, All Programs, Accessories, System Tools, and then System Restore.

    2. The System Restore window will open. Select the Create a restore point option and click the Next button.



    3. Enter a description for the restore point in the Restore point description text field and click the Create button.

    The restore point will be created and available to rollback to if ever needed.


    If you ever need to rollback Windows XP to an earlier time, on the first screen of the System Restore window, select the Restore my computer to an earlier time option and follow the prompts to select a restore point and initiate the rollback.

    How to resolve Black Screen in Windows?


    Starting your computer and seeing the disastrous black screen  means that you definitely need to see these troubleshooting black screen computer tips. I have seen many black screens on computers as I used to repair them. I am grateful that I do not have to do this any more, as I used to have literally piles of computers complaining of the same problem, a black screen problem. Now that I am not fixing computers, I have time to write tutorials and troubleshooting black screen tips for other people to learn by. It is impossible for me to mention every possible cause or solution of a black screen computer, however even if this article helps 50% of the people that read it, I will be happy.
    Troubleshooting Black Screen, this could mean a few things:
    • You were just about to load Windows and saw the logo screen and then you got a black screen in Windows.
    • You saw the usual loading screens but just didn’t quite make it into Windows. You did not see a Windows logo as it appears that you can only see a black screen in Windows.
    • You logged into Windows and then saw a black screen.
    • You were using the computer and then a black screen in Windows appeared.
    • You have logged into Windows to see a black screen with a flashing cursor.
    If you see a computer black screen and do not see anything else at all, including the usual loading screens, then your black screen has appeared before Windows has even had a chance to load. As you can see, there are many ways to have a computer black screen and therefore it is very hard to pinpoint your particular problem. Sometimes having this problem can be easily solved, but at other times it is a nightmare and hopefully these troubleshooting black screen tips will help you.
    Start in Safe Mode when Troubleshooting Black Screen Errors
    1. If you can start your computer in safe mode you should be able to choose to do a system restore, providing you have not disabled the system restore feature. Below I have a screen shot of the incensed boot options menu that you see when you press the F8 key when starting the computer. In the screen shot below I have chosen safe mode. When I pressed enter the computer will boot to safe mode.

    Last known good configuration for troubleshooting black screen problems

    2. Restart your computer and press F8 to get to the advanced options menu. Choose to start with the last known good configuration. If you are lucky enough to see a screen full of options, after an error with a black screen in Windows, never choose to start the computer normally. You should always choose a safer option right now. The two best options to try first our last known good configuration and safe mode. In the screen shot below I have selected “last known good configuration” to see if Windows start with the same files it did before the error happened.

    8 More Troubleshooting Black Screen Computer Tips
