My question is - what version Win10 should I have downloaded to replace Win7 home premium. I want to make another DVD to do the same on another laptop.
Computer has label. Nirsoft Produkey found a different key. Windows 7 has not been replaced only auto updated. Windows 7 home, drive formatted using AOMEI (wanted clean install). Windows 10 boot DVD made using Media Creation Tool on another computer. Selected Windows 10 home single language user US 64bit (trying to match computer original win7 home premium) Win 10 activation would not work with label key or produkey key. Could it be because of language and country mix ups? Called microsoft using the slui 4 command in Windows Run. Auto validation did not work after putting in all the number codes.
Talked to second operator after first operator repeated my activation process and also failed. Operator checked my label product key and it was proved to be genuine. Operator connected to my computer via internet and said that single language version cannot be activated this way. My Win10 was ?regraded?? and then at least 2 keys were tried and various operations using command prompt e.g. slmgr -upk, cpky, -ipk. Eventually after about 1 hour Microsoft (well done Microsoft) were successful in activation.
