Visual Studio Crash when typing in editor

问题

I have been using VS2010 for a few weeks but for the past few days it has been totally unusable, when i type anything into the editor Visual Studio throws an exception, then I get lots of intellisence errors (the code is fine, I can compile it if I run before trying to use the editor) - here is the log message:

This seems like it might be due to some info missing from the registry on your computer. If you go to the MS Connect website you'll find a discussion about this issue and what seems to be a solution as well.

Solution (copied from that page):

Using regedit look at the following key:

On 32-Bit Windows: [HKEY_CLASSES_ROOT\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32]
On 64-Bit Windows: [HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32]

The "(Default)" value should be one of the following:
On 32-Bit Windows: "C:\Program Files\Common Files\Microsoft Shared\MSEnv\TextMgrP.dll"
On 64-Bit Windows: "C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv\TextMgrP.dll"

Looks like a problem with an extension or add in. Disable them all then re-enable one by one and see if one of them is acting up..
