Re: Keeping Win7, can pry it out of my cold dead hands...
@ 6+ hours update....
that was not a normal update, it was most likely an 'edition' upgrade.
Visually there's not much difference between these two, but the upgrade is actually a full Win10 reinstall that migrates all applications and user data to the newly installed OS.
That slow 6+ hours surprise upgrade time is what happens when you install Win10 (and keep it unmanaged with WSUS) on a mechanical slow-as-molasses 5400rpm HDD in a computer that's really designed only for home use, or at best as an office typewriter.
if your time is so critical then please ask your company to at least consider replacing those mechanical HDDs with SSDs.
For replacements, I usually prefer to use 5-year+ warranty SSDs even if the 2-year ones are cheaper. In the long run, it's safer to use higher quality ones.
