Programs - Uninstall using Command Prompt in Windows

Hi Brink, I'd love to but I can't My laptop was fine when I switched it off last night but ever since my husband tried to switch it on this morning I haven't been able to get into windows. There was an update done before I switched it off last night and as it usually does it's made it not work. When I get this fixed I'll be switching off the auto updates cause this happens every time, usually after I fiddle around with it for a while it starts working again but this time it's not

yeah that was the 2nd, 3rd, 4th & 5th thing I tried, after trying startup repair. I'm trying to avoid wiping the whole system cause although I have a back up on an external harddrive I have a funny feeling there's some files on the laptop that were put on after the last backup. I've managed to get the computer to open in safe mode but it still wont open windows and when I try to get it to open in safe mode with the command prompt it hangs at avgidsha.sys which I've read is common so I'm trying to delete AVG completely via the command prompt in the hopes that it might restart

THanks Brink, will that work without being able to get into windows?

cool i shall give it a go, thanks

all fixed :) It got a bit hairy when I skipped the line that said plug in the external harddrive and I tried to transfer the files to the usb stick but luckily i checked it on the other computer before i went any further, then of course the other computer couldn't see the external harddrive even though it always had before lol, it did eventually, all files are transferred, reinstalled windows and have spent the afternoon trying to get the internet working again, it is but I'm still not sure what I did to get it that way roflmao. Am finding it nice not to have to deal with the quirks that the company i got the laptop from put on it before i got it, bare slate my way Thank you so much for all your help.
