Hello,I cleaned my laptop with bitdefender then I switched it off with the power button because it froze;but when I started up again ,I lost all icons and I cannot get access to anything nor log into the internet.
thanks to all of your kind replies ;
but I brought it to the local Staple store and all it needed was to hold down the F8 key till I can run it in safe mode ,then I restored it to the time before the download of an update from Microsoft (annoying one).
This solution can help anyone else in my situation ,instead of having to buy another software like MS windows XP or serviced by some stores.
