How to repair PC errors free

What type of errors are you getting ?

If you want to prevent errors:
Always Shutdown your PC the right way.
Install as little software on your computer as possible.
Do a checkdisk from time to time. (Open Command Prompt as an Administrator - Type Checkdsk to run it)

If you have errors:

What are the errors where and when are you getting them?

I have found that all these applications advertising registry cleaning and speeding up you computer do not work for me. So I would NOT recommend installing just any software from the internet claiming it will repair your errors.

Looking forward to your response..
