Restart the PC, verify free storage and internet access, run the Windows Update troubleshooter, and retry. Do not interrupt firmware or BIOS updates, and back up important files before using repair-install or reset options. Leave the PC plugged in and give it at least an hour before you call an update stuck, since large updates can sit at one percentage.

Exact questions
Common questions about “Windows Update is stuck or repeatedly fails”
Why does Windows Update stick?+
Corrupted update files, low space or a driver problem.
Could a restart help?+
Yes, restart and try again.
What if it keeps failing?+
Note the error code and search that code.
Should I pause updates and try later?+
Pausing updates and retrying after a restart can clear temporary problems. If a specific update fails repeatedly, note its number and search for that update on Microsoft's support pages.
Should I free disk space?+
Yes. Updates need several gigabytes of free space. Remove large files and run Disk Cleanup, then try again.
Does the Windows Update troubleshooter help?+
It resets components and can clear stuck downloads. Run it from settings, restart and check for updates again before more advanced steps.
How long should I wait before assuming it is stuck?+
Large updates can look stuck for an hour or more. If the percentage has not changed for several hours and the disk light is idle, restart the computer and run the troubleshooter before trying anything more.
Can a low battery or unstable power stop the update?+
Yes. A laptop should be plugged in and the computer should not sleep during the update. Interruptions can leave the update stuck, so keep it powered and awake until it finishes.
