I run Windows 7 Ultimate x64. Recently, after Windows Update ran, I could no longer connect to the web. All my hardware and drivers checked out fine. I could even run a VMWare guest OS on the machine that could connect to the web.
I dropped back to a previous Restore Point and all was well. Naturally, Windows Update ran again that night and the problem returned.
The only clue I have is that Dyn Updater reports that I may have a problem with WINHTTP.DLL.
Thanks in advance.
