Have a mate's laptop to fix and I'm stumped on how to fix this issue. After logging in the screen stays black and explorer.exe doesn't load. I have to ctrl+alt+delete every time to manually start it and after that it works fine. In safe mode it loads automatically. I've looked at fixes online and a lot of them say to change the windows shell registry key in winlogon as there are other parameters but this laptop's is the way it should be (just explorer.exe). I have done a Windows Vista startup repair but have not done an actual repair as I do not have Vista Home Premium disks, only Ultimate which as far as I know doesn't repair other windows installations. I have ran a SpyBot and Avast scan, both giving results but none of them fixing this issue. Anyone got any ideas?
