Windows Phone Emulator is doing a complete OS boot…
If this starts happening whenever you launch the Windows Phone emulator
Can I suggest following the advice from Eric Fleck on this thread.
- Delete the emulator saved state files (C:\ProgramData\Microsoft\XDE)
- Reinstall the January Update
- Open an elevated command prompt
- Execute msiexec /update WindowsPhoneDeveloperResources_en-US_Patch1.msp
That fixed it for me.
