If your upgrade to Windows 10 build 10122 keeps failing, here's a workaround

If you're rocking a Surface Pro 3 and have found that the upgrade to Windows 10 build 10122 fails before it completes, there's a simple workaround for this that allows you to complete the install.

SP3 users who are getting rolled back on upgrade to 10122, try from CMD: rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN

Gabe Aul responded via Twitter to users who reported that their installs were failing at around the 18% mark, and further stated that it was affecting around 1.2% of all Windows Insiders based on their telemetry data - this equates to around 40,000 users that have been affected by this issue, if we go by the latest known figure of about four million Windows Insiders.

@lucienimmink This should work for any device failing at 18% during driver migration (telemetry shows this is 1.2% of installs on 10122)

Other users have reported that this issue happens with the Surface Pro 2 as well, and the fix (below) should work for those devices too:

Open command prompt as admin and enter the command; rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN

Of course, an OS preview isn't for everyone, and especially those that need their Surface Pro for work, or as a main device. If you're not ready to install the preview just yet, we have you covered: check out a gallery of Windows 10 build 10122 here, known issues here and also what's new in this build here.
