In reviewing the need to upgrade to Windows 10 from 8.1, the question
comes up about the size of the Windows 10 installation on an existing
8.1 install?

Will Windows 10, increase the size of the OS install appreciably.


What about a tablet will a Windows 10 install increase the size of the
OS install on a tablet? (HP Stream 7 32 gb)

As far as specific numbers, no one will know exactly until the final W10
is released. And, of course, it will depend on which one you get. But!
Ask yourself this: When has a new Windows release's footprint ever
been SMALLER than the previous release?
