  1. I can't rename the folder $Windows.~BT because it says that the folder is open in ohter program, and order me to close it... but there isn't any program or files opened. o.O

    1. I couldn't either until I restarted the computer. Only then was I able to rename the files without a hassle.

    2. Thanks CLARK KHO for your input. i am assuming that renaming the folder finally fixed the error for you.

  2. I followed the instructions regarding renaming the -bt folder. Win 10 appeared to install without problems. After "configuring files" I got a message in the same window to restart the computer. It installed several updates, but when it came up after the restart, it was still in Win 8.1. What gives?

    1. Hi Phil, There should have been some Issue on Configuring files stage so you were rolled back again with windows 8.1.

      Please try to upgrade to win 10 again and see if everything goes through.

  3. You guys rock! Thanks for the help!

  4. We have a winner! Thanks!

  5. When going through the first set of steps and continuing to have the error occur I then followed the next set of step but continue to have an "Error 0x80070091: The directory is not empty." dialogue pop up. I followed all of the steps perfectly even trying multiple times to recreate the process but with no avail.

  6. won't give me permission to rename $windows.~BT. Tried safe mode, tried diabling windows update, tried disabling Windows Trusted Installer - nothing works...help

  7. Renaming the $Windows-BT folder worked like a charm.

  8. I have tried every "fix" that has been offered from erasing the software download file to disabling the startup programs and all non Microsoft services to using the update trouble shooter. On all of my family's pc'c I get the same error 1900107. My neighbours are getting it as well. I think your update craps out when installed. I hope you find a solution some day.

  9. Very many thanks for the advice, I don't know how you found out this information in the first place, but you've helped me. Great job!

  10. It worked on my Win10-PC!!!! So thank You very much!

  11. It worked for my win10-pc! So thank You very much for sharing Your expertise!
