Tweaking.com - Disable or Enable Data Execution Prevention (DEP) allows a user to easily turn DEP on or off. DEP can cause some programs to crash, and as such, you may need to turn it off. As with the majority of Tweaking.com's programs, this one is available in Windows Repair but can still be used on its own.

As a plus, for a system where DEP is grayed out by windows, you can still enable DEP with this tool. DEP will still be grayed out, but it will be working.
There are scenarios when you need to keep DEP off like when you want to continue using older programs. With DEP on these older programs crash.



DEP is a security feature that can help prevent damage to your computer from viruses and other security threats. DEP can help protect your computer by monitoring programs to make sure they use system memory safely. If a program tries running (also known as executing) code from memory in an incorrect way, DEP closes the program.
