Add Secure Delete to the Windows 10, 8, and 7 Context Menu uses SDelete and registry files to add Secure Delete to the right-click Context Menu, as explained in our tutorial.
To accomplish this, we're going to use SDelete from Microsoft Sysinternals and Mark Russinovich. SDelete will delete a selected file and overwrite the blank space three times, making a recovery difficult, if not impossible.
Open File Explorer (or Windows Explorer) and copy either sdelete.exe or sdelete64.exe to the C:\Windows\System32 folder. If you're not sure, copy sdelete.exe because it works for both 32-Bit and 64-Bit computers.
You will need to have administrator permission and click Continue when prompted.
Double-click Add Secure Delete to Context Menu.reg (sdelete.exe) or Add Secure Delete64 to Context Menu.reg (sdelete64.exe).
Right-click on any file to verify Secure Delete is now available.
To uninstall, make more than three passes, or get more detailed information, see our tutorial here.
