I'm trying to access my File Explorer options so I can set "This PC" as default for File Explorer instead of Quick access, and every time I click "Options" I receive the following error: This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."

I've tried looking this issue up, I've attempted both fixes in this article and for the regedit one I get to \HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ and have no Explorer file after so I cannot delete a "Disallow Run" folder, and for the Group Policy fix, everything under "User Configuration"->"Administrative Templates"->"System" is already "Not configured" so the error doesn't seem to coming from there, either.

Any help is greatly appreciated as this has been bothering me for awhile now.
