Windows 11 Pro reactivation without digital licence linked to Microsoft Account

Dear Forum,

Running Parallels 18 on Macbook Air M2. Everything was working perfect until I accidentally deleted the iso file for the Windows. I ran a Win11 Pro instance. I contacted parallels support through FB and they suggested reinstalling Parallels and the VM. I did so, but my Windows key was not linked to my Microsoft Accont, in fact I do not have a Microsoft Account with the email address that I am using for licencing Parallels.

Please advise as I cannot get my Windows product key back from Parallels in any way.

Many thanks for your kind help.
