"Save your personal docs elsewhere" that is precisely why I want to get full control of my C drive.
Where are these files that is preventing you from copy/paste to a different drive?
Not the folders/Libraries they live in, but rather the individual files.
For instance...if you select and copy your 'Documents' folder...that folder carries the NTFS permissions of your current user. You can copy it, but later access might be a pain.
The files within it it do not. You can copy/paste them freely, to wherever.
If you can't, then your system has other issues.
Also, this is why MS recommends NOT using the insider builds for your daily driver system.
