Windows 10: Upgrading from Windows 8.1 with a Simple Update

Windows-10: Moving In-Place

The MMS event, held at the Radisson Blu at the Mall of America is heavy on tech and seeded by MVP and Microsoft heavyweights.

During his session today, Michael Niehaus has delivered some information that will be interesting to most of you, and primarily those wondering about options for update to Windows 10 once it releases publicly. Attendee Daniel Ratliff captured the moment on Twitter today, showing how migrating from Windows 7 or Windows 8 will require an in-place upgrade, but those moving from Windows 8.1 will only need to apply an update from Microsoft.

So, for those that chose to utilize Windows 8.1 in their environment, there is a sort of reward in that the upgrade will be quick and simple. For those migrating from Windows 7 or Windows 8, the upgrade will take a bit more time, effort, and planning.


I had a spare 8.1 box at home and painlessly performed an in-place upgrade on it to the Win10TP (not Enterprise.) It worked the first time, and the only bugaboo was that it took 90 minutes to complete, but in-place upgrades take a lot longer anyway. I did the same between the original TP build and 9860–worked fine the first time. I actually never considered that it would not work, which is why I tried the in-place upgrade the first time…;)

In Win8.1 it is exceptionally simple to do this, I found. Simply boot to the 8.1 desktop, download the Win10TP iso from Microsoft, mount it as a DVD under 8.1 from its hard-drive location, and run the setup from there (removing the burn step entirely) and your in-place upgrade will be accomplished. I also found this method works very well for a repair reinstall, just like in WinXP, except there’s no need to boot from the OS DVD…! This method retains *all* of your personally installed programs & files regardless of their source, just like the old XP repair reinstall, as far as I can see so far.
