One of my windows 7 laptop is still waiting Microsoft to validate my computer’s specific but my another one has been notified and successfully automatically updated. After a couple of weeks waiting, this weekend I lost patience and decided to find other ways to update my windows 7 to windows 10.
|Validating Windows 10 for your PC|
One way I found is to use Microsoft media creation tool. Microsoft has provided a URL to download software for those who do not want to wait and want to update to win10 by themselves: http://www.microsoft.com/en-us/software-download/windows10 .
This Microsoft URL provides 32-bit version and 64-bit version tools for different devices. A blank USB or DVD (and DVD burner) with at least 4 GB of space will be needed if you want to create media.
Since my laptop is running on 32-bit version Windows 7, I downloaded this 32-bit tool MediaCreationTool.exe. When ran it, something happened (Something happened 0x80070490 – 0x20016) windows shows up.

After searched Internet I found there is a useful tip to fix this annoying and meaningless error message.
By adding a new DWORD (32-bit) AllowOSUpgrade value 1 under registry tree \ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade, it will enable automatically windows update to download windows 10 into your machine.

After closed Registry Editor window opened by command Regedit, Windows update automatically started to download Windows 10 updates.
|Downloading Windows 10|
After download 100% completed, it started the process to prepare for Windows 10 installation.

You may get a license agreement window, accept it, windows will ask you to reboot your machine to start this update. Waiting updating for around 30 minutes, there are a couple of rebooting during whole process. You machine’s screen will show percentage and notify you where the procedures is. Eventually you will get into lovely Windows 10 screen.
