Microsoft Visual Studio – Fixing a Broken Toolbox (in Visual Studio 2010 SP1)

When starting Visual Studio 2010, it would hang for about 30 seconds trying to load the toolbox. I found this solution online and it worked for me:


I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so:

“Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage

After finally get fed up with the issue, I started researching it and decided that I’d share the steps that I took to resolve it below:

  • I first made a complete backup of my registry.
  • I then removed the following key: [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftVisualStudio
  • I went to the following directory: C:UsersYour Name HereAppDataLocalMicrosoftVisualStudio10.0 and created a folder called bk and moved the .tbd files to that folder (they are hidden so you will have to show all files). I then removed the .tbd files in the root directory.


  • I then launched Visual Studio 2010 SP1 again and it recreated those files and the problem was gone.

Anyways, I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer.

Thanks for reading.
