ndmmxiaomayi SG If you want the effects like svchost.exe not appearing (you see a lot of svchost, but you see none of them on taskbar), there are ways of course. Ask those spyware creators.
KrenByte SG I heard there’s a software which hides all the windows (even the ones on taskbar also disappear) with a shortcut. Useful if parents suddenly spot check. Not sure what’s the name though
