    If I don’t find the file, is it okey to go to next step? (the folder shows hidden files)

    I followed the instructions with attention, but, when I want to rearm again it produces the following error: On a computer running Microsoft Windows non-core edition, run ‘slui.exe 0x2a xCC004FE00’ to display the error text. When I do it says:”The SL Service reported that activation is required to recover from tampering of SL Service trusted store.
    Any solutions on that? Thank you very much.

    I was unfortunate enough to think that you didnt have to use the key when you got a computer. I was ignorant of technology at the time so have mercy on me. I got my pc for christmas 2 years and never knew you had to put the key in before a certain time or you are done for. So i basically lived off of slmgr rearm for the last 2 years but alas MS has caught up with me and no matter what i do (Ive tried everything) nothing works. Im getting so frustrated at MS and myself for not doing something in the past. 🙁 Does anyone know of any way around this at all? Could i buy a new windows disk or key and install it, if so would it keep all of the contents of my hard drives? Thank you for reading (If you did) 🙂
