Repairing Windows Security When It Won’t Open in Windows 10
As avid Windows 10 users, we’ve all encountered occasional hiccups with the operating system. One common issue is when the built-in Windows Security app refuses to open. This critical program handles your antivirus, firewall, and other key security settings, so not having access leaves your PC vulnerable.
After consulting numerous Windows 10 forums and experts, we’ve discovered several techniques to revive the Windows Security utility when it’s unresponsive. By leveraging insider tips from experienced users, you can troubleshoot why Security won’t launch and fix the problem for good.
Ready to reinforce your system’s defenses? Let’s dive in.

Repair Windows Image Files with DISM
If SFC comes back clean, our next move is the Deployment Image Servicing and Management tool, or DISM. This powerful utility can mend damaged Windows image files that might prevent Security from loading properly.
Follow the same steps above to open an Admin Command Prompt. This time, type "DISM /Online /Cleanup-Image /RestoreHealth" and press Enter. DISM will now scan and repair any corrupt OS image files.
After the scan completes, restart your computer and test if Security opens again. Running SFC and DISM in tandem often resolves even stubborn app issues caused by low-level corruption.
