Its not this easy mate. Mouse as well as keyboard will stop working at
this stage. Your solution can't work.
Do you only see your background image? That is not quite the same (to
me) as the desktop not being loaded.
If this is the case there is generally malicious software afoot.
You need to get your desktop working, then you can resolve your
potential malware issue.
From your background image, press CTRL-ALT-DEL and open Task Manager.
Look at the Processes tab and if the explorer.exe process is not
running, launch it.
Click File, New Task and in the box enter:
%windir%\explorer.exe
Click OK and see if you get your desktop back.
If explorer.exe is already running, it is likely the object of the
affliction and may need to be replaced (not hard).
It explorer.exe is running, End the Process anyway and launch a new
one as indicated above.
Report back for what to do next.
