Make insertion mouse cursor visible in dark Visual Studio editor

Edit: In Windows 10 this setting is in a different place:

1. Open settings
2. Click Personalization
3. Click Themes in the right sidebar
4. Click Mouse Cursor
5. Select the Scheme called – Windows Black (system scheme)
6. Click Apply

Original Answer:

I have the same problem in Visual Studio 2012 (Dark Theme) on a Windows 7 guest system running inside VirtualBox.

I have found a slightly better solution:

Basically, you can globally change the cursor scheme:

1. Open Control panel
2. Open Appearance and Personalization
3. Open Personalization
4. Finally – click Change mouse pointers.
5. Select the Scheme called – Windows Black (system scheme)

Makes your cursor nicely visible against the dark background while also working great on light backgrounds.
