Donating SSD to another PC & clean install

I have a Dell PC that is running very slowly on W10
After all usual stuff, clearing junk, defrag etc., still not good enough - as its currently on an old HDD, going to install an SSD for the OS.
I cant install any more RAM

Been advised to do a clean install rather than clone across an OS that might have issues.

This SSD will come from another W10 PC (one I'm using today) I will install a new larger SSD in this main PC (using Clone SSD software) so that will be easy enough.

I have 2 questions ....
wipe of donated SSD ?
Do I need to wipe or change something on this SSD before I install it in the Dell - is there a boot log or something I need to delete to avoid it trying to boot off this 'wrong OS', or will using install media override that.

license Q
The Dell is currently all working on-line, (just very slow) and therefore full valid W10 license ... but I have no license code (was upgrade W200 > W7 >W10)

I had to delay upgrade for some months as I could not find admin account password .......... I have now found this, so want to 'protect' myself, against being locked out again after upgrade.

How can I get to view the account & license details, I have full access from admin account.



Just don't want to get the 2 OS versions mixed up and end up being locked out of PC.

 

1. Yes...as the 2nd PC hardware is different from current PC, so always do a clean install in this situation.

2. With 2nd PC and OS a new license will be required. So you'll need to buy what ever version of windows you want to install on 2nd PC.
