I have a Windows Vista Home Premium Laptop with a genuine license key. I was wondering if that key would be accepted as a valid key for Windows 10 if I downloaded the ISO from Microsoft and tried to install it.

Thanks.

PS: The Vista copy I have currently is loaded with bloatware. If I downloaded a Windows Vista Home Premium ISO (say, torrent) and tried to install it, would this key work?

  • Likely not, as Vista installations are not eligible for a free upgrade to Windows 10. You'll need to purchase a new Windows 10 license, and you'll need to clean install ("keep nothing"). If you have a valid Windows 7 or Windows 8.1 key, you would be able to upgrade. – bwDraco Jul 31 '15 at 15:56
  • Don't download any Windows ISOs from anywhere other than Microsoft or your computer vendor's official channels. You may luck out, but odds are against you if you do that the copy you get will have malware or other elements you do not want installed on your PC. – Michael Kjörling Jul 31 '15 at 16:09
  • Here are some related questions. Download Windows Vista Home Premium to use with my own key? and Where can I download windows vista legally? The Windows 10 installer only accepts Windows 10 keys – Ramhound Aug 4 '15 at 13:52
  • Very old topic I know, but for the sake of correctness I'll post anyway. I have installed Windows 10 many times with Vista and Win 7 keys. Microsoft even said it would work when they said you can clean install your free Win10 upgrade. – djgandy Nov 24 '16 at 15:16
  • @djgandy I know you didn't use a Windows Vista license key to activate a Windows 10 installation. – Ramhound Nov 25 '16 at 21:30

No.

What makes you think it would?
