METHOD 1: Show All Icons in Taskbar Notification Area
It might be possible that the Windows 10 upgrade icon is present in Taskbar but its hidden. You can show the icon by using following steps:
Right-click on the date/time in Taskbar system tray and select "Customize notification icons" option. It'll open a new window. Now enable "Always show all icons and notifications on the taskbar" checkbox and it'll show all icons in Taskbar.
If the Windows 10 upgrade icon was hidden, it'll appear now in Taskbar.
METHOD 2: Enable Get Windows 10 (GWX) Using Registry Editor
Just set the value of DisableGWX DWORD to 0 or delete the DWORD. The method also contains ready-made Registry script to automatically enable or disable GWX app and its icon.
NOTE 1: Also go to following key in Registry Editor:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\UpgradeExperienceIndicators
And in right-side pane, make sure values of UpgEx and UpgExU are set to Green. If their values are different, change them to Green.
Also make sure Genuine string is set to 1.
If you can't find above mentioned values in "UpgradeExperienceIndicators" key, you'll need to create them manually. You can match values of all available strings
Restart your computer to take effect.
NOTE 2: If you see another key with the name REDUCED under UpgradeExperienceIndicators key, it means the "Get Windows 10" app is running under reduced mode. It happens when your computer hardware is not compatible with Windows 10 upgrade. In such case, as mentioned in point 4 of "Important Things to Know" above, the app icon in system tray will automatically appear after Windows 10 launch date i.e. July 29, 2015. So you should wait of Windows 10 launch. If you don't want to wait, you can try to delete REDUCED key and make sure the entries present in UpgradeExperienceIndicators key match with the above screenshot.
