To prove the random/eclectic nature of my blog, here’s a completely technical issue that I got 1 hour ago that made me panic. Despite a lot of Googling, there was nothing obvious that provided the solution to the problem, so (after I found the solution) I thought it was a good idea to post it (just in case it helps someone else):
I have got Symantec PGP Desktop installed on my laptop. I changed my Windows password this morning. Immediately afterwards, Windows gave me a message which warned me that something seriously wrong had occurred and that I had one minute to save my work before it would automatically reboot.
After rebooting, I was presented with the Windows 7 logon screen, but with only one user: PGP SSO
If I clicked on that user, it did nothing. I could not ‘switch user’, so there was no method for me to logon with my correct username/password.
Reboot the laptop. Click F8 immediately during the bootup process. Choose “Safe Mode“. Logon and click “Start” button. Type “Regedit” to open the registry editor.
Right-click on the following key: HKEY_LOCAL_MACHINE\SOFTWARE\PGP Corporation\PGP
Create new “String Value” with the following name: DISABLEWIDESSO
Enter the value as: 1
The problem seems to be caused by a bug in Symantec PGP Desktop: BUG REPORT: PGP Auto-Login process for Windows halts and displays PGP SIngle Sign-On icon with no manual method to login
Here is where I originally got the hint from: HOW TO: Disable the PGP Single Sign-On auto-login feature
