last known good configuration

About this tag
The last known good configuration is a Windows startup option accessible by pressing F8 during boot. It restores the system to the most recent registry and driver settings that allowed a successful startup. On WindowsForum.com, users frequently turn to this feature when troubleshooting boot failures, blue screens, or freezing after driver changes, registry edits, or system modifications. Common scenarios include recovering from STOP 0x0000007B errors, resolving BSODs like 0x0000003b, and bypassing issues caused by removing upper/lower filters or disabling drivers. While effective for recent configuration problems, it may not resolve deeper corruption or hardware failures, and some users find it unavailable when boot issues are severe.
