WINHTTP.DLL problem after Win 7 update

Topic

New Reply

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.

Any ideas?

Thanks in advance.

Do you have SP1 installed?
It is possible that it could be corrupted. Let’s use the System File Checker (SFC) tool to see if it can find any missing or corrupted system files. If so, it will attempt to repair and/or replace them. Follow these steps to run an SFC scan:
1. Click Start
2. In ‘Start Search’ type cmd, then right-click cmd and click Run as administrator (provide administrative credentials if prompted)
3. At the command prompt type “sfc /scannow” (no quotes), and then press ENTER
When the SFC scan is complete test to see if the issue is resolved.

I tried your SCF suggestion. It did not find any problems. I still cannot connect.

Unfortunately, the advice than can be given will probably give you some work. That would be to restore to a known point in time where everything would be working and then install the updates one by one. Once you hit the problematic one, uninstall it and configure Windows Update not to offer it again.
