I have a serious problem with my computer. It all happened around the time of a routine Windows Update...
As of this morning I am unable to open most applications. For instance, if I attempt to open Microsoft Office I receive a popup: "preparing to install..", then: "error 1719- The Windows Installer service could not be accessed".
When I attempt to open iTunes: "iTunes has detected a problem with your audio/video configuration".
I can hear the normal sound effects when clicking around through Windows, but there is no audio playback for media/youtube/etc. My web browser is working fine..
I did a system restore twice and have had no success. I assume this has to do with my update? Or maybe a virus? I have no idea..
I tried uninstalling the Windows Updates, but it didn't seem to help. There are quite a few security updates for Microsoft .NET Framework 4 Client Profile that I'm unable to uninstall for some reason, but I was able to uninstall the main Windows Update.
I also noticed that I'm unable to playback any video files (mp4, flv, etc.). Another weird problem - I'm unable to open any of the subheading in Control Panel (e.g. uninstall a program, view devices and printers, etc.); only main headings can be opened.
Also, if I open my task manager sometimes there are maybe 40-50 instances of dllhost.exe - COM Surrogate.. not sure what this is?
Please help!! I need to get homework done!
Thanks in advance for any help
