I bought this 6 months ago.  It has been buggy since day 1.  I am above average on computers- I fix and update my families computers.  Windows and especially Windows Explorer is incredibly slow.  I have spent many hours on this to no avail.  And windows 10 locks up sometimes.  And the mouse stops working sometimes.  And Chrome locks up sometimes.  Etc.  Yesterday I set a restore point before downloading a few apps from the Microsoft store.  I did not like the apps, so I tried to restore to the restore point that was only a couple hours old.  I got the "restore initiating' screen for several hours.  I forced a shutdown by holding the power button in for several seconds.  Now I have nothing, it won't start.  I am using one of our Lenovo Thinkpad laptops that have all lasted years with no problems, even after upgrading to Windows 10.  This desktop is going in the trash, and I will not buy any more desktops or any more 'restored' computers.
