Supposedly it fixes any missing or corrupt windows files, click start>run and type this or copy and paste into the box sfc /scannow Good luck.
I have a notebook that I had to reinstall everything from Windows XP down. Everything is working properly now except when I close Outlook. It doesn't happen everytime, but I continue to get an error message saying that winhttp.dll was not found. I have to click out of it a couple of times before it goes away. Can anyone help me with this?
