This may not be the right thread for it, but I’m having a computer problem. I run XP. A couple of weeks ago I logged on and got the error message: Windows cannot find logon.exe. I checked, and that file is still on my computer. [One of the main symptoms, btw, is that I can’t play videos, not any, At All.] After reading as much as I could online I decided it was probably a registry error. I ordered a CD that claims to repair and recover Windows XP/VISTA + DOS - BOOT. I tried to use it but I’m just not technically savvy enough. (I thought an icon would pop up with the words, ‘Repair registry’, I’d click it, and problem solved.) Any help anybody can offer will be profoundly appreciated. Thank you in advance.
