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.


I have 2 dedicated ssd in my desktop for win 8.1 and win 10

Today I did a full clean install of the latest win 10 evaluation version
10130 and my programs.

The size of the installation is no different than 8.1. It may even
be slightly smaller.
