How to Set Windows Security Exclusions in Windows 11

Windows Security is Windows 11’s antivirus utility that scans files and processes in the background. However, its real-time background scanning can sometimes wrongly identify legitimate programs and processes as malicious (known as false positives). Such antivirus interference can block some software from launching.

you’re able to ensure Windows Security doesn’t sound false positive alarm bells for certain programs by adding them to its exclusion list. Programs, folders, and other files included on that list are excluded from the Microsoft Defender Antivirus scanning. This is how you can set Windows Security scanning exclusions within Microsoft’s latest desktop OS.
