= Windows Ten Activation Issues = if you get can not activate windows ten on a laptop (lenovo, ibm, dell etc) it is probably because the bios has a built in product key that has somehow mismatched with windows ten it will probably say go buy a new copy from the store with an error code like 0xc00400c4 ? (that will vary) run a command prompt in windows ten and paste the following command into it '''{{{wmic path SoftwareLicensingService get OA3xOriginalProductKey}}}''' and press entry it will return key info that you will need from there goto settings, activation and at the bottom click the change activation key enter the key and go next if there is still an error call microsft at 905 568 0434 press 2 for business and then goto activation activation will think you have an old style activation windows open just keep pressing 0 then # 0 then # until they transfer you to a person. from there ????
