Windows 11 Cursor Chaos Tied to Optional KB5120998 Update
Windows 11’s optional KB5120998 update (Build 26200.9278/26100.9278) is reportedly breaking mouse cursor customization (size/color and default schemes) and resetting wallpapers, with additional font issues; Microsoft says it’s investigating and notes the problem appears after installation, advising affected users to uninstall the update to restore cursor settings—the issue typically resolves upon removal and could be followed by a rollback or emergency fix.
