Is it safe to fix Windows 11 activation issue?

When I was installing Windows 11 on an old laptop, the first issue I ran into was activation — the key was lost, and the system kept reminding me about it. In discussions on various forums, I often saw suggestions to “fix it easily” using special utilities. That made me wonder: do these methods really work without consequences, or are they a potential trap? I decided to talk to others who have already dealt with something similar.
