To open Registry Editor, click Start, click Run, type regedit, and then click OK.
Choosing Last Known Good Configuration provides a way to recover from problems such as a
newly added driver that may be incorrect for your hardware. It does not solve problems
caused by corrupted or missing drivers or files.
When you choose Last Known Good Configuration, Windows restores information in registry
key HKLM\System\CurrentControlSet only. Any changes you have made in other registry keys
remain.
