Follow this steps
if you don’t see a message from the get windows 10 app on the taskbar, if the upgrade files have been downloaded to your PC, you can start the process via Windows Update.
However, you won’t be doing it through Windows Update in the modern Settings app. If you try you will see the following message:
You need to use the desktop version of Windows Update. To do that, use the keyboard shortcut Windows Key+X or right-click the Start button and select Control Panel from the power user menu – which is also available in Windows 10 (it’s called the Quick Access menu in 10).
Scroll down to the bottom of the Control Panel and select Windows Update.
You’ll see the Windows 10 upgrade is ready. Just click the “Get Started” button.
Check for Issues
Note that the upgrade might fail at first. I retried it three times before it started to work. Once it does begin, just like with the upgrade in Windows 7, you’ll need to agree to the
After that, you get the option to begin the upgrade now or schedule it for a later time. Again, just like upgrading Windows 7, you only get a three-day window to schedule the upgrade.
After it starts, just sit back, grab a coffee because the process can take quite a while.
You’ll get the familiar screen shown below that lets you know where the upgrade process is at. If it seems to hang, just be patient, especially the first couple of weeks…a lot of people are upgrading at the same time. Also note that your PC will restart a few times, just let it do its thing.
After it completes you’ll get a Welcome Back screen and you start clicking through the on-screen setup instructions.
Unless you’re particular about how you want your Windows settings, just go with Express Settings during setup (versus custom settings). It allows you to get up and running a lot faster. If you want to make any adjustments, you can do that later.
Also, keep in mind that there will be updates waiting for you. Windows 10 requires that you install updates automatically, so you will get them without thinking about it. But, if you want to make sure you have everything updated right away after the upgrade completes, go to Settings > Update & Security > Check for Updates.
