Enable disable auto reboot on system crash (Blue Screen Of Death)

In Windows NT, Windows 2000, and Windows XP, a blue screen of death occurs when the kernel or a driver running in kernel mode, encounters an error from which it cannot recover. This is usually caused by an illegal operation being performed. The only safe action the operating system can take in this situation is to restart the computer. As a result, data may be lost, as users are not given an opportunity to save data that has not yet been saved to the hard drive.

By default, when the Windows XP and the Windows 2000 operating system crashes an automatic reboot of the system occurs.

Blue screens are known as "Stop errors" in the Windows Resource Kit documentation. They are referred to as "bug checks" in the Windows Software development kit and Driver development kit documentation.

If you want to resolve the auto reboot of the system problem when operating system crashes, you can modified this behaviour in two ways; via the registry or using the System Properties property sheet.

Via Windows Registry
CAUTION: We strongly recommend that you back up the registry before you make any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the keys that are specified. Read the document How to make a backup of the Windows registry for instructions.

Click on START > RUN and type regedit
Then click on Ok button.

The Registry Editor, will be appeared.
In the left pane of the Registry Editor, navigate to the following subkey (making double click on each registry key):

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
CrashControl

Now, in the right pane of the Registry Editor locate and make double click on the following registry subkey named AutoReboot

If not, make it. In this case, in the right pane of the Registry Editor, right click in the white space and choose NEW > DWORD Value to create a new subkey.
Name it AutoReboot.
Now, make double click on it.


A new window will be appeared.
Modify the value in the field named Value data (by default is 1).
Set the value data for this subkey to:

0 (read ZERO) to disable Auto Reboot;
1 (leggasi UNO) to enable Auto Reboot.

Then click on Ok button.

Exit the Registry Editor.

Restart the computer.


Via Control Panel
To avoid the inherent danger of editing the registry, the same results may be obtained by using the procedure detailed below.

Open System Properties via Start > Control Panel > Performance and Maintenance > System (System Properties may also be opened using the WinKey+Pause key combination)

Select the Advanced tab and then click Settings in the Startup and Recovery section.

In System Failure section, clear the checkbox next to Automatically Restart to disable Auto Reboot;
or put a check mark next to Automatically Restart to enable Auto Reboot.

Click OK and OK to exit.
