I really wanted to test Windows 10 migration before I updated my Windows laptop. I decided to install a copy of Windows in a VM and upgrade that copy to Windows 10. Once I had Windows installed, I run Windows Update and got all the latest updates for my installation. But, the Windows 10 logo on my taskbar (Get Windows 10) did not appear. I restarted a couple of times just in case and run Windows Update again, but still nothing.
Even though I could download an ISO image of Windows 10 or force the update through wuauclt.exe /updatenow, I discovered that the best way to do this is through the task scheduler which initiates the upgrade process as intended. Before you begin, you should navigate to C:\Windows\SoftwareDistribution\Download and delete all the files in that folder.
