I switched the new drive out and put the old on in, intentionally to try out Windows 10.
One word: AWFUL!
I like the classic (XP) style, but all the new Win10 has is the modern crap. Window frames were very thin and difficult to recognize when windows overlapped. Slidebars were to thin the mouse pointer had trouble latching onto them. I have hated the ribbon menus since it was introduced around Win8 or so.
It didn't take me long to switch the hard drives and back to Win7. Even now, when I want to do some ‘real’ computing with Word or Excel, I load the old XP ‘97 version because I can find the functions I want. The new ribbon menus are clumsy, gaudy, inefficient and in some programs take up 1/3 of the screen real estate. They are even worse on my laptop.
I am staying with Win7 as long as possible. However, I have noticed some ‘entities’ are requiring browser/program updates and will not work with the Windows 7 versions.
When it doesn't work, you have to go kill at least one process to get it going again.
Heck, updating a relative small directory may take more than just a moment.
