Why Widnows10 app doesn't show in windows 7 , 8 and 8.1

Symptoms

If you have Windows 7 or 8.1, you may be expecting to see the Get Windows 10 app, a small Windows icon in your system tray. This app gives you the prospect to get a free copy of Windows 10.

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.

Cause

Some imaginable causes are:

1. If your device is or has been linked to a domain, or is completed by a system administrator, it may be blocked from the upgrade reservation. Check with your IT administrator.
2. If your copy of Windows is not genuine, or if you have a Volume License copy (intended for industries), 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 Information Base article 950929 for more information. If you have a Volume License copy, it does not qualify for the free upgrade.

If neither of these reasons are the case with your copy of Windows, try the Resolve steps below.

Resolution

Try running this Windows troubleshooter to resolve the issue.

You can also try these manual solution steps, but the troubleshooter will be faster and easier.

1. Check your Windows version, edition, and Service Pack level.
1. Windows 7: Open System by clicking the Start button, right-clicking PC, and then clicking Properties.
2. If your edition is Windows 7 Enterprise, this PC is not qualified for the free Windows 10 upgrade, because it is a Volume License edition intended for business use.
3. 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
4. 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.
5. 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.
6. If your version is Windows RT or Windows 8.1 RT, this device is not eligible for the free Windows 10 upgrade.
7. 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. Commands for promotion 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

2. Make sure Windows Update is turned on - for instructions to turn on Automatic Updates, see Information Base article 306525. Then check to see if the needed 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 Bundle 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.
1. Windows 7: also run the command dism /online /get-packages | findstr 2952664 If this update is not installed, install it now.
2. Open Internet Explorer. Press Alt + H, and select About Internet Explorer from the menu that appears. Make sure you have Internet Explorer 11. If you have an earlier version, download Internet Explorer 11 from https://www.microsoft.com/en-us/download/Internet-Explorer-11-for-Windows-7-details.aspx?id=40902
3. Windows 8.1: also run the commands
   dism /online /get-packages | findstr 2976978
   dism /online /get-packages | findstr 2919355
   If these are not installed, from the Start screen search for Check now, and select Check for updates to install those updates.

After you have completed all of these updates, reboot your device.

If, after running the expert or doing the manual steps, you still don’t see the icon, your device may not be compatible with Windows 10. The troubleshooter should inform you if there are compatibility problems. If that is the case, you will not be able to reserve a copy at this time. More information will be available later regarding what you can do about that. For more information about Windows 10 requirements, go to: https://www.microsoft.com/en-us/windows/windows-10-specifications

Please note that while the easiest way to get the free upgrade is to reserve, you can upgrade for free even if you don’t reserve, providing your device is compatible with Windows 10 and has a genuine activated copy of Windows others .
