Unwanted stuff

[Peachson]

I have so much stuff on my computer for one reason or another. Either it was there when purchased or given, downloaded, or attached with something else, like Microsoft Windows.
Can I safely scrap some of it. What can I scrap & how do I recognise it. What could go wrong. Thanks.

Hopefully you have two HDD partitions,you can put all the stuff you really need on the second partition..........then I would suggest that you do a fresh reformat and install windows clean over the newly formatted space........installing only the elements of windows which you need.........
