I am unable to disable/remove some extensions in Visual Studio 2015, including extensions like the "Multilingual App Toolkit" and "MySQL for Visual Studio" that I have installed myself. In several cases, both the `Disable` and `Uninstall` buttons are grayed out in the Extensions and Updates manager.

[![Visual Studio Extensions - showing greyed out disable and uninstall options](https://i.stack.imgur.com/S3e35.png)](https://i.stack.imgur.com/S3e35.png)

I've tried starting VS as administrator, and also launching VS in safe mode (using `devenv.exe /safemode`).

Why is it not possible to disable some extensions, and what is the correct way to safely disable them?

You can manage extensions from Visual Studio only if they use standard .vsix installer. If they use other installer like .msi you typically use Control Panel - Programs and Features to uninstall them.
Windows *Control Panel -> Programs and Features* can uninstall most of those addons. 

For anything else, there is an awesome simple utility: [Total-Uninstaller](https://github.com/tsasioglu/Total-Uninstaller). It can uninstall virtually anything, including hidden stuff. 

Warning: uninstalling too much can make Visual Studio crashing / unusable and can even damage Windows installation. Make sure to back up important info before proceeding.
