Hello there, my friends. I have a Dell computer with genuine Windows 10 Home OEM preinstalled. The key is not on any sticker on the computer, and I searched and found out that the key is at the BIOS. Ok, then I tried to activate my Office with the "KMSAuto_Net_2016_v1.5.0_Portable" tool and accidentaly activated my Windows. Now it says that my Windows key is invalid and Windows can't be activated because I'm not connected to my organization's KMS server. I want to revert this "KMS activation" and activate Windows again with my genuine key. How can I do so? (revert KMS to OEM activation) Also, how can I get my Windows OEM key from the BIOS? Thanks in advance!
