Locate the file FixShell.cmd and double click it to run the script. A cmd window will open, then close after a short while.
For the next part of the fix, you will need to have your original Windows disk ready as you may be asked to insert it.
Open Windows Task Manager again, and click New Task... again,
Type in sfc /scannow (Note the space between sfc and the slash)
Hit OK.
This will now check the integrity of all your windows system files and if required install new ones from your windows disk.
When all is complete, reboot your computer and let me know if you have your desktop icons and taskbar back again.
