Every program that you try to run just opens as a mass of characters in Word.
The solution is to do a System Restore – but if you try to do a System Restore it opens as a Word document!
You need to do a System Restore from a Command Prompt – but how do you get there?
Use CTRL ALT Delete and select Task Manager.
Left click “File” and then hold down the CTRL key whilst left clicking “Run new task”.
Now you have a Command Prompt!
At the command prompt, type cd restore, and then press ENTER.
Next type rstrui.exe , and then press ENTER
After a short wait the System Restore window will open.
You may want to select the option to show more restore points.
Select a restore point previous to the start of the strange behaviour and left click the “Next” button.
