[Windows 10] Digital License (HWID) & KMS38™ Generation

[thepixy2]

I was sold a used windows 10 (64 bit, pro) computer, windows version 1903. The seller did not tell me that my activation was via a KMS activation key, which will expire in 180 days. The seller did not share the KMS tool he used, or even tell me which one, so I have no way of knowing if it was KMSPico, or some other tool. I usually clone my system hard drive before trying anything new, so I can “go back” and have a fresh start. I don’t understand how to use the KMSPico, but I've tried other KMS activators and know they work. HWID sounds like a better and more permanent solution, but I have some questions: 1) If I want to try your HWID tool, do I have to first remove the existing KMS? If so, I’m not sure how because I don’t know which one it is. 2) If I try your tool and it doesn’t work, can I go “back” to one of my clones? I ask because somewhere in your instructions I saw that the process is “IRREVERSIBLE”. Is that because your tool is writing data to the motherboard bios? I just want to make sure I can “go back” if it doesn’t work, and the word “IRREVERSIBLE” is scary!
