Hi. I think I replaced my original windows 8.1 64 with a fake one. The scenario of what I did is given below: I purchased a hp laptop with original windows 8.1 64 preinstalled. I downloaded Microsoft Office with toolkit from torrent because I did not want to buy ms office. First I installed the office setup.exe as per instructions. Then I opened the Microsoft toolkit. I had no idea how to use it. I pressed the windows logo instead of the office logo. Then I selected windows 8.1 and I clicked activate, backup, check, check status, etc randomly. I had no idea what I was doing. Now I think I replaced my original windows 8.1 64 with a fake one. I cannot update my windows and it is showing error code 8024402F. Please help me on what to do. Please advise me whether I replaced my original windows. I want my original windows back.
