Microsoft Emphasize Signature Edition Tablets

Microsoft started emphasizing Signature Edition tablets, 2-in-1 tablets, and other computers that run Windows today in their own Microsoft Store.

A Signature Edition Windows computer is a clean install of Windows without additional trial software that expires after 30 days or so, or other trialware and often annoying software that you may never use, and that clogs up the computer by using much of the capacity of your processor and RAM, even if you're not using the software itself.

So, Signature Editions deliberately rejects software that isn't Microsoft's own, but not Microsoft software like Office which is still included with most Windows tablets today.
