(Cracked)Digital license linked with Microsoft account

Back in 2020 , I bough my new pc with window that I think it’s a cracked version (I don’t sure) because I didn’t get any boxes or keys. After that I linked it to my Microsoft account and i haven’t got any error ( I think if it’s cracked version , it shouldn’t be link to Microsoft account and haven’t got any update further)
I have 1 pc and 1 laptop. It’s activated in pc first but after I’ve tried to install window on my laptop and log in to my Microsoft account. First it hasn’t been activated yet ,But after i see the option “…recently changed hardware…” i clicked it and now both pc and laptop has been activated (after i searched on the internet . They shouldn’t be activated by just one license and it’s supposed to be cracked version)
So my question is
1.How can i untie the cracked license from both?
2.If i buy a genuine key and change the product key , will cracked version be replaced?
3.If i buy a new laptop that have pre-installed key and log in with my Microsoft account that link to this cracked license,Will the crack license replace the pre-installed license?
4.If i clean install window and use the window that link with digital license, Will it contain virus or malicious things?
P.S. I have planned to use legit key soon but i have to ask for make me sure.

Sorry I’m new here. I don’t know how to reply other’s reply

Yes, I know that i should buy legitimate key. I’m gonna use the same Microsoft account.
So the question is
1.How to untie cracked key from Microsoft account?
2. Can the new legitimate key replace cracked key that link to my Microsoft account?
3.If i buy a new laptop that have pre-installed key and log in with my Microsoft account that link to this cracked license,Will the crack license replace the pre-installed license?

If it is a cracked key, if your Windows is activated and therefore a digital license registered on Microsoft's servers, there is no longer any point in trying to legalize the system. Each time you do a clean install the computer will activate with the digital license not with the cracked, stolen key.
