Well here I am at last. Had a complete nightmare!!!
Every time I opened a browser, then tried to click on something, I would get the error "Windows has encountered a problem and needs to close" and it would do this repeatedly, in an endless loop.
So I never got to read your last post!!!
However, a little yellow icon appeeared in the system tray to re-install the security updates and SP3 that I had uninstalled. So, I've reinstalled this, but explorer STILL doesn't work properly, and the above error message appears.
All my system restore points had gone, so I couldn't do a system restore. I tried to re-install IE8 again, but because of the problem I couldn't.
So, I had a brainwave, I've just installed Firefox, and WOW!!! It's SO FAST compared to IE!!!
AND it works perfectly, so I've managed to get into this forum now to type this message!!!
I obviously have to get used to the different features, but I'm sure it can't be that hard.
I'm SO impressed with the speed!!! It's like lightning!!
Or maybe I just got used to the slow IE8, which is why I wanted to uninstall it in the first place.
I'm an instant Firefox convert now, I wish I'd done this years ago.
I'm giving up on trying to fix my IE now, as I don't need it.
Thanks for all your help, but its Firefox for me now. I must say again its miles faster than IE!!
