I recently upgraded an old Windows 8.1 version to a newer December 2014 DVD using the Upgrade Setup assistant, some bundled updates in this version introduced errors.

I'm unable to remove these updates since they are part of the system.

Is it possible to use an older 8.1 RTM DVD and Upgrade (actually downgrade) using the Setup wizard?

Another alternative would be upgrading to Windows 10 Technical Preview, which is obviously a risk.

    No; This isn't possible; The problem you face is that the first rollup Update 1 actually changed the build of Windows. Where as the build number I don't believe changed second rollup ( Update 2 ) – Ramhound Feb 5 '15 at 18:15
  • why do you want to get rid of the November Update? Which issue do you have? – magicandre1981 Feb 6 '15 at 5:59
  • Windows Store Apps and PC Settings are not working anymore, more details on that here. – Gabriel Feb 6 '15 at 8:59

As mentioned in the comments, It cannot be done. Instead I upgraded to Windows 10 Technical preview, luckily it fixed previous update errors while keeping most programs and settings intact.
