Computer suddenly slow and starts up with non-changeable classic theme
The computer was perfectly fine yesterday; normal speed and using the default Windows 7 aero theme (save the background obviously).
Since today the computer is suddenly slow from the start-up already; When it comes to the "configuring windows" screen it takes about a minute instead of the second to get to the login screen. Then when I log in, everything is in the classic theme. A warning also pop-ups during start-up.
Here's a screenshot where you see the task bar in classic theme while it should be aero theme. You also see there the warning on start-up. It basically says it can't connect with a Windows server, namely the System Event Notification Service.

After start-up other problems are occurring.
First of all, parts of the computer has become slow. The most notable is right-clicking on the desktop (and only the desktop!), it will take ages before the right-click menu is loaded.
Secondly, I can not change the theme, was my initial thought to do. All themes except the classic themes are greyed out and not selectable.
Thirdly, the antivirus, Avira Antivir, starts up disabled, and whatever I try, I can not enable it. This started to happen after a few start-ups.
So yeah, quite bothersome problems. I have tried the following solutions:
- Scan my computer with Avira. I've scanned every single file my computer has, but my computer didn't find any viruses. This scan was done before Avira started acting weird.
- System recovery. I first send it back to yesterday, which was right before an Windows update. The computer was fixed after the system recovery, but after a reboot every problem was back. Now for some reason none of the system recovery points are working, including the first one I tried.
So far I have one possible conclusion: It's the Windows update from yesterday. It installed only one update, which was a definition for Windows Defender, KB915597 definition 1.129.1102.0 to be precise. It's also the only difference between today and yesterday, and before and after the first system recovery. Sadly this update re-installs itself immediately after a system recovery, and I can't find anything about this update on google, so I can't say for sure this is the cause.
Anyone knows how and why this happens and how to fix this?
