Windows Security is Missing from Windows

Question

Brother Installed a game in my laptop, the game setup disabled the windows security but now there in no windows security in my settings, no virus and threat protection. Nothing. It just shows blank screen or this prompt sometimes.

Is there any way I can solve this without reinstalling windows?

Answer 1

Best just perform a repair installation which allows you to keep all your files and apps.

Go to the third download option at the following link and download Windows 11 Disk Image (ISO) for x64 devices. Make sure you choose the correct language option to match your installation.

https://www.microsoft.com/software-download/windows11

Once downloaded double click to mount the ISO, or right click and select Mount.

Double click on setup.exe

Next click on Change how Setup downloads updates and select the option Not right now.

If the option to Keep personal files and apps is greyed out, abort the installation.

Answer 2

Download and extract this registry file then boot into safe mode to apply:

Windows security is working fine now. Thank you.

Answer 4

That's great. Go into Virus & threat protection settings and make sure there's no unwanted exclusions set.

To cleanup delete FRST64.exe and the C:\FRST folder.

Good luck! :)
