Ah.. such a mess they make. if that is such unique piece of info then they must put inside battery compartment and not at the place where it has most chance of fading. Absolutely <profane> thing. I have ever other number with me but uh.. They must be able to retrieve from recovery discs i think but nobody is going to tell how!!
Thanks a lot for this life hack. Your trick helped me save a lot of money that I might have had to pay for a new license 🙏
Thanks for passing this on. One of the last group of 5 digits of the product key was unreadable. I didn't have any acrylic paint but used ground-up pencil lead instead and it did the trick - magic!
I use a piece of magic transparent tape over the paper COA BEFORE it becomes unreadable.
