If the percentage appears stuck on a particular number for a long time, the update process may be stuck. If you see a percentage number on your screen and it's increasing, leave Windows alone as long as it appears to be making progress.
Windows may just need some time to finish the process, especially if it's a big update and your hard drive is slow and full. We recommend waiting two hours, just in case Windows is doing a lot of work. However, if this message has appeared on your screen for a long time, you may need to restart your PC. It's common for this message to appear on your screen for up to five minutes.
Depending on how big an update Windows has to install and how slow your computer and its internal storage are, this process could take a while to complete. Be patient and give Windows some time to finish installing updates if this message appears on your screen.
