Hello,
I have been trying to upgrade my windows 8 laptop to 8.1. However update fails due to error 0x8007001f. I have found out about this error is that an attached device is not working. How can I determine what is causing the issue?
Before finding out what the error specifically ment, these are the troubleshooting steps I've tried so far:
(1)Unplug all external devices, (like USB flash drives, mouse)
(2)A clean boot startup
(3)Turning off virus protection
(4)Installing the KB2864247 UPDATE
Thanks in advance to anyone who responds.
(I've also heard that I should try to upload the setup logs file as a possibility, but I don't understand how to do so from this link: http://technet.microsoft.com/en-us/library/hh824819.aspx)
