  1. Created a new PC system, but my old key doesn't work


    I've had for a few years a Windows 8.1 key that I use on my own next systems, swapping them relatively regularly. However, when I tried to do that on the newest one, I get error 0x803FA067, saying I don't have a valid digital license or product key. My key is valid as I copy-paste it from my purchase order email. I thought it is because my account Devices was still seeing some old machines, which I removed one of them from there, but this didn't help. What is more frustrating is when I try to use the Troubleshoot I get "Try again later Something went wrong on our end. We're working on it." and

    Windows doesn`t start. Authomatic repair doesn`t work.

    Thanks again!!

    I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

    I`ll do it and I`ll be updating this thread when I have the report.

    I ran SeaTools. These are the results:

    Does it mean my HDD is useless?

    internet explorer doesn´t load any page

    I tryed all 3 methods but got no success.

    The funny thing is that IE is working fine on a new created test account (like method 3 suggests) but after this I switch back to my account and confirm IE is useless.

    In sum IE not working on my account which is the admin one, but it is working on other accounts I create.

    Doesn´t make sense to me...
