Disable Automatic Reboot During System Crash

In Windows 7 and Windows XP, the default behavior of the operating system after a system crash or blue screen is to simply restart. Sometimes an automatic reboot can fix the problem and you don’t have to worry about the actual error.
However, most of the time once your system crashes or if you get a blue screen, it will not be a one time event. If there is some software or hardware problem with your computer, your system might crash often or you might get more BSOD’s.
In this case, it’s good to be able to actually see what the error message is that caused the crash. You can do this in two ways, either via the System properties or by editing the registry.

Windows 7, XP – Disable Automatic Reboot during Crash/Blue Screen

In Windows 7, you can turn off the automatic restart after a system crash by going to System properties. Right-click on My Computer and choose Properties. Note that the procedure for Windows XP is nearly identical.
Now click on Advanced System Settings on the left hand menu.
Click on the Advanced tab and then click on Settings under Startup and Recovery.
Finally, go ahead and uncheck the Automatically restart box under the System failureheading.
Click OK and close all the previous windows. Now when a system error or crash occurs, you will be able to see the entire message instead of it just flickering on the screen for half a second.

Disable Automatic Restart via Registry

Note that you can also disable this option via a registry key, so it could be scripted and run on many computers at once.
Navigate to the following registry key listed below:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
Now find a key called AutoReboot. A value of 1 means that automatic restart is enabled and a value of 0 means it is disabled.
That’s pretty much it! This is a very useful feature that will give you a lot more time to review the error that caused a system crash or failure. If the error message flashes and then disappears, it’s because automatic restart is set. Enjoy!
