SUMMARY
This article explains how to change the Registry to boot to a different CurrentControlSet. This might be necessary if you used LastKnownGood and restored a previous configuration that didn't have all the desired services, printers, shares, and so on.



MORE INFORMATION
WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

To change the Registry to boot to a different CurrentControlSet, perform the following procedure:

 Boot into Windows NT and run the Registry Editor (Regedt32.exe). Go to HKEY_LOCAL_MACHINE/SYSTEM/Select, which will display the following parameters (your data field may vary depending on the ControlSet being used):

Current:REG_DWORD:0x3

Default:REG_DWORD:0x3

Failed:REG_DWORD:1

LastKnownGood:REG_DWORD:0x2

 Look in ControlSet001 through ControlSet003 to find the ControlSet that should be restored. Change the data in the following Registry key:

to the appropriate ControlSet. For Example:

Current:REG_DWORD:0x1

Default:REG_DWORD:0x1 Change the LastKnownGood:REG_DWORD:0x2 to the previous Current data. For example:

LastKnownGood:REG_DWORD:0x3

 Exit Regedt32 and reboot the server.

NOTE: If the server fails during reboot, use the LastKnownGood configuration to get back to the previous setting and Registry options.</li></ol>
