Hi
I have been attempting to uninstall my version of SQL Server 2008 R2 as we are migrating to SQL 2014 and I need to leverage the default instance. I have managed to uninstall all the SQL Server 2008 R2 features except for the database engine. When I attempt to delete the Database Engine it hangs (left it for over 4 hours) at the SqlEngineConfigAction_remove_unconfigrc_Cpu64 section within the uninstall. After checking in the Detail logs for the uninstall I can see that it is stuck at the following step:

It never gets past this step. I have had to restore my computer 3 - 4 times today because the only way to stop the uninstall was to reboot my machine and then restore so I could attempt to uninstall again.
Before I started the uninstall this last time, I made sure that all SQL Services were disabled; that all service/websites that talked to SQL were disabled but I am still running into this issue. The closest issue I found on that net that was close to the same symptoms (hanging on SqlEngineConfigAction_remove_validation_Cpu64) but I don't have the registry item of AppCompat in the folder to even try setting that registry key to a different value.
Hopefully someone else has encountered this and knows how to fix it because my next steps are a complete reformat but I don't really have the time to start that.
Thanks for your help,
