Pls help me l can't activate anti cheat

l can’t activate anti cheat it says missing important windows update can you give my link for the updates for windows 8.1

Have you taken a look in your Windows Update center? If you have a valid copy of Windows you should have the ability to download and install any Windows updates you’re missing.

I had the same problem with my Windows 7 and I believe the update which fixed the anti-cheat not displaying was a Microsoft .NET framework update for Windows, but you’re probably better off installing any updates the action center says you need.
