Question Delete Old OS

I'm preparing a new build. My old PC's C: drive is a 1TB HDD with Win7 on it and all my software installations.

On my new build I was planning to use an SSD for Win10.
Can I just plug my old C: drive into that system and delete the old OS so I don't have to back up the entire drive and reformat? I know I'll have to inplace reinstall much of the software, but it would still be easier.

I'm thinking Win7 may have some protection on their files keeping me from cleaning it out completely.

protection on their files
I have never heard of such thing.

Recently I 've put the Windows installation disk (was of Windows 7x64), and deleted the volume, containing the Windows, and I formatted the drive.
(there was just one useless warning, where I answered 'Yes').

And no problems.

Window has a bad habit of protecting their files from 'accidental' deletion.
I know that typically goes for the active operating system, but you never know what they'll do with strange user permissions or hidden partitions or whatever.

Not the way you're envisioning this.
You can't move to a new platform, do a full OS install, keep your current applications, and change the OS from 7 to 10.

Too many moving parts all at the same time.

For the new hardware, a new install is always recommended, usually required. And with that, a reinstall of all your applications.

When I went from XP to 7 it was a clean install since I went from 32 to 64 bit. That said, I did drop all my program files and such back on the drive. If they failed to run, I just did an in-place re-install of that program.
I guess in this case just about everything would need to be re-installed, but any program that keeps settings in its directory would preserve them.
