Hi, I recently downgraded my apple software for better stability and everything went downhill from there. Ever since then, only my account (the admin account on the computer) boots properly. The Guest account and any other new account I create have a black screen after login. Explorer isn't starting automatically and it won't run manually either using Task Manager. Unfortunately, I don't have a system restore point that I can use and I don't have a Vista Boot/Repair disc with me. I googled this a little and tried some known solutions, but to no prevail. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell has "explorer.exe" and nothing else. Also, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution.options doesn't contain explorer.exe or iexplore.exe or any other suspicious keys. I'm an experienced user (even though I don't have a backup or systen restore for HD space purposes), so my pc is rarely plagued by viruses. I'm assuming this is a currupted explorer.exe file but I dont understand why it is booting fine for my user and none other. Also, iexplore.exe won't run under any other users either. Any help is greatly appreciated.
