Yesterday (11/02/12) Windows notified that there were a couple of critical updates available for installation. Always keen to keep my spec up-to-date I proceeded to install them. I'm afraid I don't know the details of the updates. As I did a System Restore (see below) they have been removed from the list of Installed Updates.
After automatic installing and re-starting the first thing I noticed was that the screen resolution had been changed. Fixed that through control panel. More importantly I discovered that the following had occurred:
- I could not get any sound.
- Could not get streaming video. Flash crashed every time
- Certain links within Control Panel would not function
Investigating (1) above, Device Manager reported that the hardware was functioning correctly. In attempting to resolve this via Control Panel/Appearance & Personalization/Personalization I noticed that the Sounds link indicated No sounds and I could not click through from the link (see below) to change anything (this happens with a few other Control Panel options).
I can find no way of reaching the sound properties. All links are non-functioning.
For (2) I uninstalled Flash Player using the Flash uninstaller, cleared out the registry of any remaining entries for it (yes there were still a couple) and re-installed it (v184.108.40.206) and re-started PC. On first re-install I had no success but tried same process again and did get it to stream video (no sound). However when I started PC today we are back to the same problem.
I have also cleaned registry with no improvement.
Having drawn a blank with these two problems I then did a system restore to the point where the Windows updates occurred. This has not changed anything so I am really stuck as to know what if anything I can do. The system and applications generally are working fine. Networking and Internet connection is fine. As the machine came pre-loaded with Win 7 I do not have a Windows Disk.
I am very frustrated with what appears to be a glitch caused by a Windows update. Any suggestion please.
