2/ Also I can't access the task manager either by control alt del or by right clicking the task bar and selecting task manager there. I've searched on this and found a number of different methods to supposedly fix this but haven't been successful so far. Here's what I've tried so far:
Click Start, Run and type this command exactly as given below: (better - Copy and paste)
Download and run this REG fix and double-click it.
Click Start, Run and type Regedit.exe
Navigate to the following branch:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies\ System
In the right-pane, delete the value named DisableTaskMgr
Method 4: Using Group Policy Editor - for Windows XP Professional
Click Start, Run, type gpedit.msc and click OK.
Navigate to this branch:
User Configuration / Administrative Templates / System / Ctrl+Alt+Delete Options / Remove Task Manager
Double-click the Remove Task Manager option.
Set the policy to Not Configured.
3/ Lastly I cant access the cmd screen. When I hit cmd into run the black screen shows up but its not accessible. The cursor doesnt come either.
Would appreciate any help!
