Thank you

My Windows 10 pc is now unable to open to the desktop after starting a thorough scan using the pc tuneup l just renewed, then restarting my computer after about 30 minutes when it hung up at 13%.  Initially, I was able to get to the desktop, opened pc tuneup and reversed the file and registry changes that had occurred in the scan process.  I then rebooted only to receive a Microsoft message that said there was a registry error and it would attempt to repair.   I have not been able to get to the desktop since getting that Microsoft message.   I only see my cursor arrow and the little blue rotating ball (which is jumping around eradically).  Any suggestions?   Thanks.
