If you experience download stagnation (User discovery always displays: fbl_impressive Professional 10159 is downloading update 0%) or prompts for error codes, or 32-bit system users cannot receive updates, You can try our recommended reboot Windows Update to resolve it.
Windows build 10159 download stays at 0%
Let's try the "Fix Me" button first. This button is located in the settings → update and security →windows update → advanced options, and then in the "Get affiliate version" find the "Fix Me" button. A normal user does not display the button, which displays "Deactivate member version".
Fix Me
If the repair option is displayed, the current version has a new receive issue. After clicking, wait for the repair to complete, then reboot the computer and try to receive the update again.
1. Close the current settings window
2. Start Task Manager
3. Click "Details" (already full mode of users can go directly to the next step)
4. Go to the Services tab
5. Find Wuauserv Service (quickly click on the keyboard W and u key two times to locate)
Find Wuauserv
6. Right-click the service and select Restart Service
After restarting the service, turn on "Settings" again to check for updates, and if you are lucky you will find that the download is over (it may be a superficial phenomenon before it is stuck). If you need to download, wait patiently.
The best way may be to wait for the next WIN10 version to be pushed. If you can't wait, consider rolling back the previous version or reuse the official ISO image of the old version of the clean installation, and then try the upgrade again.
