Resetting Windows folder

[neate]

I downloaded QB64 (for BASIC programming) and put it my Documents folder before installing it in the Programs folder. The Readme suggested I take "write" control of it's main folder using right click/properties/security. I opted for full control thinking that it would better. I now find that it has affected all other folders within Documents. I'm not now sure whether this is a good or bad move. I've tried resetting using a restore point but that didn't change the "full control". Other Windows forum suggested solutions look very complicated which frightens me.
1. Is it risky if I just carry on?
2. Is there a windows tool that will do it for me?

Any advice would be appreciated.

Might be worth choosing 'restore defaults' under the folder menu.

Have just tried but no joy I'm afraid. But thanks ellal.

You are supposed to have full control of the documents folder.

Now that is interesting. What a relief. Thanks DiyNutJob.
