Use system restore when you cannot boot your system

If your system has failed to the point where you cannot access the Windows GUI either through booting normally or through safe mode, you may still have the chance to use the System Restore feature if you have it enabled, by running it form the command prompt.

To do this:

Restart your computer and press F8 after the POST screen to bring
up the Windows XP boot menu. Choose 'boot in safe mode with command prompt.'

DECREASE THE SHUTDOWN TIME IN WINDOWS

Whenever you give the shutdown command in your Windows PC, it forwards the request to all the running services. It waits before it tells you if any of the service did not respond to the shutdown request (waits for 12 seconds in Windows 7 and 6 seconds in Windows 8). You can then force stop them or wait for them to respond. But if you have many services running, then 12 seconds for each service is much time to wait for.


So to decrease that time we have a simple trick that can decrease this time and hence decrease the shutdown time. The trick is simple, you just need to edit a registry entry that is responsible for the waiting time.

You need to edit the registry, do this only if you have the knowledge of editing the Windows Registry.

How To Decrease the Shutdown Time in Windows :

1.Open the “Run” dialog box either from the “Start” menu, or by pressing the “Windows Key +R”,

    and then type “regedit” in the window that pops-up.
