- [ ] Quirked
- [ ] Build-time break

### Recommended Action
Internet Explorer will fail to launch an application that uses managed browser hosting controls. The previous behavior can be restored by setting the EnableIEHosting value of the registry subkey `HKLM/SOFTWARE/MICROSOFT/.NETFramework` to `1` for x86 systems and for 32-bit processes on x64 systems, and by setting the `EnableIEHosting` value of the registry subkey `HKLM/SOFTWARE/Wow6432Node/Microsoft/.NETFramework` to `1` for 64-bit processes on x64 systems.
