Windows 11 Updates Trigger False Antivirus Warnings & Cursor Glitches

Microsoft is addressing two notable issues in Windows 11. The first is a harmless glitch that falsely indicates "Microsoft Defender Antivirus is turned off," which does not impact the antivirus's functionality. Users are advised to wait for a Microsoft update to resolve this. The second issue involves mouse customization settings not saving correctly since the August 27th update, although it only affects cosmetic preferences and not critical settings like pointer speed. Additionally, Microsoft has identified a solution for a game-breaking bug related to the "inpoutx64" driver, which will now be automatically blocked when launching Arc Raiders, with plans to extend this block to Marvel Tokon: Fighting Souls. Developers at Embark Studios have also implemented fixes for affected games, except for Tokon, for which players should use Microsoft's official workaround until a permanent solution is available.
