Last Thursday, my laptop installed an auto update from Windows and nothing has been right since.
Just after the update, the computer was running mega slowly, programs - particularly those with graphics - were jerky and sound was choppy.
I eventually performed a system restore to the previous Sunday and things seemed ok again, until I tried to run an often-used and always ok application, which came up with an '...encountered a problem and had to close' message, although it hadn't actually started. The documentation with it says it uses Microsoft.net Framework and to update that if problems occur. I tried but M.net won't either repair or uninstall without the original disc or whatever. I don't have a disc or whatever for M.net - I imagine it must have been installed originally in the factory.
I couldn't figure out if it was the update which caused the app problem or the system restore which did it?
Having just moved house, I of course haven't a clue where the boot disc I made originally is and I wondered if someone could please help me out of this mess - the computer that is, not the house!!
