I have a client using Dell E6530 running Win 7Pro. seems after logging into his laptop the desktop does not load just gets a black screen with the cursor. I have searched around for a solution and tried what has been suggested I can work around it but not resolve it. If I select Ctl, Alt, Del and go to task manager and go to the processes tab and end task for explorer.exe then go to the applications tab and do new task and type in explorer the desktop loads but when I reboot it is back to the same problem. I can boot to safe mode OK. In the registry I have looked at HKEY_LOCAL MACHINE / SOFTWARE / Microsoft / WINDOWS NT / CurrenVersion / Winlogon and shell and the value is explorer.exe I have run sfc /scannow and did not find any corrupted files.
