    I am having this trouble too. Was fine to download and verify the download, but got stuck at 99% when installing it. Ended up turning the computer off completely and had to wait ages whilst it installed general updates. Have since turned it back on, but have to start the whole process again.

    Well the hang at 99 % was biting hard. I had a brand new windows 7 professional machine and wanted to go to windows 10. A brand new machine. So I figure just go for it. It hangs. I try for of the other suggested fixes . it hangs. I figure something is corrupt, I fully check disk and reload fresh - it hangs.
    so I reload, the windows 7 to factory. Install all updates - I mean ALL updates, it took three rounds of update to get windows 7 to fully updated. Then I do the upgrade and it works just fine. So! Be sure the system you have is fully windows updated before doing the window 10 upgrade.
