I believe the ContextPlus is a part of the Apropos spyware module and you were lucky enough to have an automatic uninstaller for it. There are a lot of people going through this issue right now and this is my post from a few other forums.
I have worked on this problem of a corrupted Device Manager, missing Network Connections, slow response times from Windows Explorer and Windows reactivation BS for about 10 hours and this has finally fixed the issue. I previously scanned the system with Spybot S&D, Lavasoft AdAware and Webroot Spy Sweeper but nothing picked up on Apropos.
Step 1.
=====
Download AproposFix.exe:

Step 2.
=====
Restart your computer and enter Safe Mode by pressing F8 on the keyboard repeatedly AFTER your BIOS loads and BEFORE Windows starts to load.
Step 3.
=====
Log into the account where the files you downloaded are on the Desktop. It should be an account with Administor privledges.
Step 4.
=====
Double click on AproposFix.exe and extract the files to your Desktop. Open that folder and double click on Run This.bat and follow the instructions. Restart the computer once you are prompted.
Step 5.
=====
Once you are back in Windows running in normal mode with a working Device Manager, etc. get yourself online and download FireFox and download Microsoft AntiSpyware to help you stay protected against spyware.

You should still also use Spybot S&D and Lavasoft Adware.
