VS2010 crashes when editing

Problem: VS2010 crashes the instance you enter a character or paste text into a source file. The message displayed (sometimes - other times VS2010 simply dies and disappears without further notice) is:

Visual Studio has encountered an exception. This may be caused by an extension. You can get more information by running the application together with the /log parameter on the command line, and then examining the file 'C:\Users\USERNAME\AppData\Roaming\Microsoft\VisualStudio\10.0\ActivityLog.xml'

Solution: The solution was found in this forum, which states:
It appears to be due to missing registry information. Adding the default value to the below registry key solved the problem.
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"

Win7: Restore .bat default behaviour

One of those small, very annying problems: I had managed to assign .bat files to open with my favourite cleartext editor (Notepad++ by the way), so that instead of running the bat file upon double-click, it opened in the editor. Now I wanted it reverted back to the original behavior.

I finally came up with a working solution: Just delete this registry key with all subkeys and life as you knew it before will be smiling to you again:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.bat
