In most cases, it would go past the screen in mere seconds or few minutes after it shows 100% complete. However, it’s not uncommon that people would sometimes encounter an issue where the screen gets stuck on the “Working on Updates” screen even though it shows 100% completed after waiting for a long while. Here’s why and how to possibly get around the problem.

Fix: Working on Updates 100% Complete Stuck on Windows 10

Solution 1: Wait it out

It might sound silly but most of the time giving it more time and waiting it out solves the issue without having to mess with your system. If you have waited for only 30 minutes or so, give it another 2 hours. If even after 2 hours, it still cannot go past the screen, you can then start trying other solutions.

Solution 2: Run CHKDSK

In most cases, the cause of getting stuck on the “working on updates 100% complete” screen is because of slow disk reading and writing speed. Slow disk speed is mostly due to old and overflowing hard drive that has been used for a long time without maintenance, usually happen on regular hard drive that is not an SSD. Things such as bad sectors, disk errors and viruses may also slow down your disk speed.

If waiting is not an option, the best thing you can do is to force restart your PC and run CHKDSK for your system drive. Running CHKDSK will check and fix your disk errors and bad sectors if any is found. Then, try to restart your PC again and see if it will still stuck on the working on updates screen for a significantly long time.
