2] Disconnect all external USBs
Disconnect all external USBs, accessories, media, extended display cables, Wi-Fi adapter card, etc, from your computer and then try again.
3] Try 2-3 times and see
Many times, an update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times.
4] Run Windows Update Troubleshooter
Use the Windows Update Troubleshooter from Microsoft. It resets Windows Updates settings to defaults.
5] Disable your security software
Temporarily disable your firewall, antivirus or security software, VPN, temporarily. You may also temporarily uninstall such software like Disc Burners, Defragmentors, Optimizers and all programs that startup with Windows, as some of them have been reported to create issues. An incompatible application installed on your PC could be blocking the upgrade process from getting completed. Do a thorough check that any incompatible apps are uninstalled and then try upgrading your PC.
