FIX: Write Access Denied on Drive C:\ – You need permission to perform this action on Windows 10, 8, 7 OS (Solved)

If you try to create or to save a file on the root folder of drive C:\, and you receive the error "Destination Folder Access Denied: You need permission to perform this action", continue reading below. By design and for security reasons, Windows 10, 8 & Windows 7 don't allow users (even Administrators) to save files in the root folder of drive C:\. So, when the user tries to create a file in the root folder of drive C:\  (using notepad or another program), Windows displays the error "You don't have permission to save in this location".

In Windows 7 OS the only action you have to perform in order to save files at this location (C:\) is to Turn Off UAC (User Account Control) settings from the control panel, but in Windows 8 OS (or Windows 8.1) this procedure doesn't work any more and you have to disable the UAC through Windows Registry. Keep in mind that disabling UAC on your system is not a secure practice because it may allow malware programs to compromise your system. In my opinion and according to my experience, "UAC" is a little annoying security precaution because you always have to answer to a recurring popup window for almost any action you want to perform to your computer.

In this tutorial I 'll show you how to disable UAC in Windows 10, 8.1 (or Windows 8) and resolve the "Destination Folder Access Denied: You need permission to perform this action" error when you try to create (or save) a file on the C: drive's root folder. (This solution also works for Windows 7 and Vista OS.)

3. Inside Windows Registry, navigate (from the left pane) to this key:

4. At the right pane double click at EnableLUA DWORD value.

5. Change the value data from 1 (one) to 0 (zero) and click OK when finished.*
