By design and for security reasons, Windows 8 and 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 drive C:\ (using notepad or another program), he receives a "You don't have permission to save in this location" error message.
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 8.1 (or Windows 8) and resolve the "Access Denied Error" when you try to create (save) a file on the C: drive's root folder. (This solution also works for Windows 7 and Vista OS.)
How to Disable UAC in Windows 8.1, Windows 8, Windows 7 and Windows Vista through Windows Registry.
Note: If you to modify User Account Control (UAC) sensitivity level then read this tutorial.
2. Type "regedit" and press Enter.
IMPORTANT: Before you continue to modify the registry, first take a registry backup. To do that:
a. From main menu go to File & select Export.
b. Specify a destination location (e.g. your Desktop), give a filename (e.g. "RegistryBackup") and press Save.
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.*
* Note: Set the value to 1 (one) anytime you want to re-Enable UAC on Windows.
6. Close Registry editor and restart your computer.
You 're done!
