That's what Macrium Reflect is for. Life can be so easy...

Win 10 is supposed to do it for you and revert seamlessly if done
before a couple of weeks

Actually, no.

The seamless part, is anything contained in Windows.old is preserved
very nicely. No argument there.

However, they modify the contents of your Program Files, removing
programs as they see fit, which means an attempt to revert, they
never put the contents of Program Files back.

This is why we use backup software here. *Backup* before your "free"
Upgrade installation! That's how you revert, with absolutely no
issues at all. A backup copy will keep your Program Files, the way
you had it.

So to give in to microsoft exhortation and update from a perfectly
good working system with 128 GB SSD to a FREE one which does not work
and stops what you had from working on revert You need to spend
$100.00 or so for external memory to back up to.

I do wonder what Microsoft is thinking. Perhaps most users don't
consider reinstalling Windows to be a big deal. But since you do...

I also have a 128 GB SSD primary drive, for windows and programs. That
plus a very inexpensive 750 GB (now it would be almost 2 GB) secondary
drive for multimedia and backups. And Macrium Reflect for free.

A huge conventional backup/secondary drive is about $55 (US).

I've been backing up the primary Windows drive since about Windows 95.
Never looking back. Microsoft restoration utilities were a complete
waste of time. I went through very many different third-party backup
utilities. Macrium Reflect has proved to be the best by far. It's been
flawless. And I doubt it can be any easier.

Unfortunately, seems that Macrium Reflect has removed the option to make
a Linux recovery CD, so eventually I'll need to find some way to put
their more recent version on a recovery drive. But, for now, the prior
version recovery CD works perfectly. Therefore I would recommend using
one of their prior versions for Windows 8.1.
