I am trying to update a computer for someone that is Windows 8. I was able to download the update file, then I had to restart the computer for it to update. Upon restarting it, it got to 82% and seems stuck there. I have tried looking around and see that this is a common problem. Are there any solutions to this?

I was experiencing the same problem updating on an Asus laptop. I unplugged the charger and it instantly started going up after being on 82% for an hour. It then continued all the way up to 100% and restarted.
If you have a laptop and are experiencing this problem, just try the above.
Hi Genevaflores,
To upgrade the operating system to Windows 8.1 without any issues, do the following steps and then check if the installation proceeds.
**Step 1:**Disconnect all the unnecessary external devices connected to the computer (except the mouse and the keyboard).
**Step 2:**If you are using any third-party antivirus software, you may uninstall it and check if you can upgrade to Windows 8.1.
Note: Even if you disable third party antivirus, Defender will still be running in the computer. This will guard your computer from malware and virus.
**Step 3:**Install all the available updates.
**Step 4:**Install the updated drivers for the hardware.
Step 5: Perform clean boot and then start the upgrade.
Refer to link mentioned below to

**Note:**After checking the functionality in clean boot, follow the suggestions under “How to reset the computer to start as usual after troubleshooting with clean boot”.

Hope this helps and do let us know if you need any assistance.
I also unplugged my power cord on my HP laptop and I can't believe it worked! It was stuck at 82% for an hour and a half!
I wonder what unplugging it does to jump start something because when I did I just heard a strong "whirr" sound of something starting up.
Hi Mihalis,
Glad to know that you have sorted out the issue. Your efforts to resolve this problem is very much appreciated.
Please post back if you have any questions, we will be more than happy to assist you.
Hello,
I'm having the same problem with the people here. I'm trying to update my Windows 8 to Windows 8.1, but it stops at 82% of installation. I have tried many solutions, including the one you posted and i did exactly what the instructions say, but i had no luck with any of the solutions. I would really appreciate a solution that will get me out of this frustrating position.
Thank you in advance.
Edit: I finally found a solution, for my case at least, on my last desperate attempt before going to sleep. I just simply deleted a "Windows.old" file in my local disk and retried to install Windows 8.1. Thankfully it worked out just fine. I don't know if this is a solution for everyone that's having the same problem but you can try it if you wish, it might work for you as well. I hope this helps.
