Accounts :: Lost Privileges To All Folders And Files?

Solved Windows 10 says I don't have permission to save anything. - Windows 10 Forums

However I am still running into an issue with Writing into about 50% of the folders in my C:

Two things could have possibly occurred to cause this issue,

1: I signed into my Microsoft account and from there out it wanted me to login to it to log into my PC, so I removed my Microsoft account

2: I shared a file to the OneDrive using the Microsoft account above.

There are multiple folders that the only thing I can do when I right click in it and go to "New" is make a new folder, no other options.

When I right click on the folder and go to Properties, Security tab, and try and change the settings for Users or administrators, I get the following error

Code:
An error occurred while applying security informationg to:C:Program Files (x86)TeamViewerConnections_incoming.txtFailed to enumerate objects in the container. Access is denied.

The above error applies to a lot of folders (but not all of them). My User account named Yekim is an administrator and the only account on my computer. I've tried elevating to administrator and changing the folder but it does not work.

So basically what I'm looking to do is to either give access to all files/folders on my computer to the User 'Yekim' or to properly give him administrator. Even though it does say he is already a local administrator it does not seem to apply.
