Computers are just supposed to work, grrrr! Today I got this error:
A recently installed program has disabled the Welcome screen and Fast User Switching. To restore these features, you must uninstall the program. The following file name might help you identify the program that made the change: C:\WINDOWS\system32\BCMLogon.dll
I couldn’t switch the logon screen, and I couldn’t access the internet. I ran to another PC and found the solution to this problem.
To resolve the problem and restore the Welcome Screen and Fast User Switching, you need to reset the GinaDLL entry using these steps:
[UPDATE: There have been some useful comments made below, you might want to check them out before proceeding.]
* Click Start, Run and type REGEDIT
* Navigate to the following key:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon
* Backup the key by exporting to a file.
* In the right pane, right-click GinaDLL, and then click Delete. (You need to remove the whole value, not just its Value Data)
* Close Registry Editor
