The Windows user profiles on my guest OS seem to have disappeared except for one user profile. When I start the VM all I see is the login prompt to my user profile, but there were three others there originally in this VM that I could switch to. I suspect they disappeared as a result of the last update that was automatically downloaded and installed for Parallels Mac 6.0 -- I believe that was build 6.0.11992. I don't know what build I was running prior to that, but I had only installed Parallels 6.0 a few weeks ago, so it was probably the latest one. I just noticed this today. My guest OS is Windows 7 Home Premium, 64-bit. It had 4 separate user profiles on it because it was a copy/export from my Dell laptop. Everything had been working just fine for a few weeks -- i.e. all users profiles available and working correctly in Windows 7, up until now. Any help is appreciated! Thanks in advance.
