If you have Windows 7 or Windows 8.1 but aren’t seeing the icon, this article will help you find out why, and if you can get the app.
Some possible causes are:
- If your device is or has been connected to a domain, or is managed by a system administrator, it may be blocked from the upgrade reservation. Check with your IT administrator.
- If your copy of Windows is not genuine, or if you have a Volume License copy (intended for businesses), the icon will not appear. To check this, open a Command Prompt (from the Start menu or screen, search for cmd, right-click on Command Prompt in the results and select Run as administrator), type slmgr /dli and then hit Enter. A window will appear with the channel in the Description line (Retail, OEM, or Volume), and the License Status. If your copy of Windows is not activated, refer to Knowledge Base article 950929 for more information. If you have a Volume License copy, it does not qualify for the free upgrade.
Check your Windows version, edition, and Service Pack level.
Windows 7: Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.
If your edition is Windows 7 Enterprise, this PC is not eligible for the free Windows 10 upgrade, because it is a Volume License edition intended for business use.
If Service Pack 1 is not listed, you need to install it before you will get the upgrade icon. You can download it by going to: https://www.microsoft.com/en-us/download/details.aspx?id=5842
Windows 8.1: From the Start screen, swipe in from the right to bring up the charms, and select Search, or just start typing to search. Search for pc info.
If your edition is Windows 8 Enterprise or Windows 8.1 Enterprise, this PC is not eligible for the free Windows 10 upgrade, because it is a Volume License edition intended for business use.
If your version is Windows RT or Windows 8.1 RT, this device is not eligible for the free Windows 10 upgrade.
If your version is Windows 8, you need to do the free update to Windows 8.1 to be eligible for the Windows 10 upgrade. Instructions for upgrading to Windows 8.1 can be found at: http://windows.microsoft.com/en-us/windows-8/upgrade-to-windows-8
After updating to 8.1, you will also need to install this update: http://windows.microsoft.com/en-us/windows-8/install-latest-update-windows-8-1
Make sure Windows Update is turned on – for instructions to turn on Automatic Updates, see Knowledge Base article 306525. Then check to see if the necessary updates are installed. To do this, from the Start menu or screen, search for cmd, right-click on Command Prompt in the results and select Run as administrator. Type or paste the command dism /online /get-packages | findstr 3035583 – if the update is installed, you will get a return with Package identity followed by a string of information. If nothing is returned, the update is not installed, and you need to check for updates and install it.
