Unable to open Notepad,Task Manager ,Regedit

Today Suddenly I found notepad ,Registry and Task manager is not working.
I scan for virus using Mcafee antivirus but did not found any anything.My cousin brother was using my computer yesterday may he bought some virus in his pendrive.
When I open notepad i get this error " windows cannot access the specified device,path or file.You may not have the appropriate permission to access the item ".
I tried following four solution found regarding this error but none of this work.
1> sfc /scannow command (3 times)
2> Removed antivirus
3> System Restore
4> Permission for opening a file

However I can open notepad in safe mode .

Is there any other solution except Re-Installing Windows again.

Please Help me !
