User Account Control (UAC) can help you prevent unauthorized changes to your computer. It works by prompting you for permission when a task requires administrative rights, such as installing software or changing settings that affect other users.

We don't recommend turning User Account Control off. If you do turn it off, you should turn it back on as soon as possible.

Open User Accounts by clicking the Start button , clicking Control Panel, clicking User Accounts and Family Safety (or clicking User Accounts, if you are connected to a network domain), and then clicking User Accounts.

Click Turn User Account Control on or off. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Select the Use User Account Control (UAC) to help protect your computer check box to turn on UAC, or clear the check box to turn off UAC, and then click OK.

Many users need to keep track of time in multiple time zones, there's a nice feature in Windows 7 to help users keep track of time in Multiple Time zones. The feature is multiple clocks in your system tray. This feature can display up to 3 clocks in your taskbar from 3 different Time Zones.

Click on the Clock in System tray. Next, click on the „Change date and time settings‟ to open Date and Time Window.

Click on the tab for Additional Clocks.

Here you can add up to two additional clocks .Enter time Zone and Clock Display name. Check the „Show this clock‟ box to enable the clock. Click OK.

Hover over the clock and it would show you Time in text for all 3 Time Zones (including the one your Local one).

Windows 7 makes it easy changing the Windows log-on screen.

1. Go to start, and click on Run, type Regedit & press enter there.

2. Navigate to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background

3. Double-click the "OEMBackground" DWORD key

4. Set value of the key to 1.

5. Select a background image for Logon Screen with size less than 256KB in size (Use of Image Resize software like VSO Resizer can help)

6. Copy that image into the C:\Windows\system32\oobe\info\backgrounds folder

7. Rename the image to backgroundDefault.jpg

8. Reboot, and now your logon Image would have changed.

One thing is for sure with any computer operating system, the older it becomes, the occurrence of broken or "things don't work like they used to"  become more frequent.

Take shortcuts for example. You know…the ones on your desktop or in the start menu.

You click on a shortcut that you have not used in a while, and chances are, it works as expected or you get the dreaded Problem with Shortcut error warning:

So to fix it, you re-point to the new location of the source or delete it. Now you wonder, how many more shortcuts do I have that are broken?

Well you could go one by one and click on each shortcut on your desktop or start menu and fix them. But that would take a be ridiculously long time (who wants to do that anyway).

Instead there is an easier way…

…and that way is to use a utility called ShortcutsMan from nirsoft.net.

ShortcutsMan is a standalone program,that does not require any installation or additional DLLs. To use it, just download it, copy the executable (shman.exe) to any folder you prefer (after it's unzipped) and run it.

A few seconds after running ShortcutsMan utility, a list of all your desktop and Start menu shortcuts will load in the main window.

Now. what's cool about ShortcutsMan, it wall automatically display broken shortcuts in pink. No need to hunt them down, one by one.

To try fixing a broken shortcut,  just check the box next to a broken shortcut (you can select more than one shortcuts at once), and either delete them, resolve them or save the shortcut's details to HTML/Text/XML file.

The first thing I usually do is have ShortcutsMan fix the shortcut by resolving it. This process searches your computer and points it to a valid file name (typically the orignal file name may have been changed or moved to another folder).

To resolve, select the check box next to the broken shortcut (pink color), then right click on it and select Resolve Selected Shortcuts.

If it can not resolve, then I usually delete the shortcut (otherwise if I really used it often…it wouldn't be broken in the first place). You can also edit and fix shortcuts yourself directly in ShortcutsMan by right clicking on a shortcut and select Edit.

ShortcutsMan is a great utility to have around to help clean up your system of dead shortcuts. If anything, having the capability to display all shortcuts on my desktop or under the Start menu in one interface is a big time saver. Either they get fixed or deleted. Real simple.

You can download ShortcutsMan from nirsift.com.

Autorun is the most likely way to infect your computer. To prevent this we can disable autorun feature in Windows.

Press Start button ->Run.

In window that has appear type gpedit.msc and press OK button.

At the left part of "Group policy" window select "Computer configuration"->"System". Select "Turn off Autoplay" at the left part of screen when "System" is select.

Double click on "Turn off Autoplay". Point to "Autoplay" and in the drop-down list select "All drives".

Press "Apply" and "OK" buttons.

The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:

1. To open a command prompt, click Start and then click Run. Copy and paste (or type) the following command in the Open box and then press ENTER:
   cmd
2. At the command prompt, copy and paste (or type) the following command and then press ENTER:
   netsh int ip reset c:\resetlog.txt
   Note If you do not want to specify a directory path for the log file, use the following command:
   netsh int ip reset resetlog.txt
3. Reboot the computer.

When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol. The reset command rewrites the following two registry keys:

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ 
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\ 
				

To run the manual command successfully, you must specify a file name for the log, in which the actions that netsh takes will be recorded. When you run the manual command, TCP/IP is reset and the actions that were taken are recorded in the log file, known as resetlog.txt in this article.

The first example, c:\resetlog.txt, creates a path where the log will reside. The second example, resetlog.txt, creates the log file in the current directory. In either case, if the specified log file already exists, the new log will be appended to the end of the existing file.

When facing a system crash or startup up problems on Windows Computers, troubleshooting the problem can be difficult to resolve. The first step with recovery is to use Windows Safe Mode option during startup. One Safe Mode option that will help troubleshoot boot problems is to enable Boot Logging which will create a log and help identify the device or driver that is causing the problem during startup.

When Boot Logging is enable, Windows boots normally, until the device or driver that is causing the problem either crashes the system or completes starting up but causes an error message in the Event Log. While booting, Windows creates a log file that lists every step processed that is attempted and completed.

You can then reboot in to Safe Mode and review the log file named ntbootlog.txt. The log is stored in the %SYSTEMROOT% directory (normally C:\Windows or C:\WINNT folder). Below is an example of ntbootlog.txt log file on Windows XP (Vista log is similar):

To enable Boot Logging on Windows XP and Vista, boot your Computer, and during startup continually press F8 until the menu screen appears:

NOTE: screen shot is from XP. Vista menu will look slightly different than XP.

Press F8 to display the Advanced Menu screen and select Enable Boot Logging

You will be returned to the menu screen and you should see Enable Boot Logging in blue displayed at the bottom of the screen (don't worry if this screen is not displayed and Windows starts to boot):

If the problem does not cause Windows to crash, and after startup has completed, you can review the ntbootlog.txt file. Look for any signs of problems loading device drivers. If you find problems, go into Device Manager and disable the device or uninstall the program, then reboot again. If the problem does not occur then you know it was that device and you should check the vendor website for new drivers or known issues.

If your problem does cause Windows to crash, reboot into Safe mode by selecting Safe Mode from the Advanced Menu screen. When reviewing ntbootlog.txt file, look for events that were attempted to load but not completed. More than likely the problem will be toward the end of the file (since that was the last item logged before crashing). When you identify the problem, either uninstall the application or go in to Device Manager and disable the device. Reboot your Computer and see if the problem still exist. If it boots without crashing, check the vendor website for new drivers or known issues.

If you are still having problems, enable Boot Logging again to see if new events are logged after you have disabled the device or uninstalled the program. If you are unable to fix the problem, you may need to have a Computer shop troubleshoot the problem for you.

Notes on Boot Logging:

• Boot Logging can only be enabled from Safe Mode. Once it is enabled, it only logs during the current boot. It will not log during the next reboot unless you enable it again from Safe Mode.
• If an existing ntbootlog.txt files exist, the next time Boot Logging is enabled, Windows will append to the existing log file.
• It is a good idea to have Windows create a new log when there are no problems or after you have added new devices. This will allow full logging to occur and will let you compare with a log when problems exists.
