When I try and update windows I got one to download install but the second one comes down okay but when its trying to install it, it stops at around 40% with this error code (0x800f0831) I've spent many hours on google since every place I've gone has a different point of view on solving this issue. Now I'm hoping but don't deserve more help from great members here but should someone decide to take a crack at it I would be much obliged. Cheers
WU will fail if you used any single tweak . M$ dont like you to tweak there os here i am again saying there own os but not yours .
First run this in an elevated cmd prompt: Code: sfc /scannow if it found errors, run this in an elevated cmd prompt: Code: findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" You can find the filtered log on your desktop.
@duster340 - Tell us what iso's you are downloading and from where. Verify the file hashes after downloading.
You should still provide a bit more information, but generally this error means that one or more of the following packages required for installation are missing or are faulty.
Its not a ISO as stated in another reply. Just an update from Microsoft that downloads 100% but once it wants to install it gets about 40% then an error code (0x800f0831).
@pm67310 No its a legit Windows 10 Pro Enterprise from my son who has a media Company. I installed it off a flash drive usb 3.0. I guess it looks like I'm going to have to re-install Win 10 but not looking forward too it! Thank you all again for your valuable input. A super group of members who make this forum outstanding. I really appreciate all of you even though my original post was quite vague. ;(
Okay, so what update is failing? (KB number). Btw, I have seen updates fail at first, then successfully install after some time later, without me ever understanding why...
Finally got the KB number which is KB5019959 which is causing the errors. I'm changing ISP's so by early December once I have my new ISP I shall do a rest on Windows. If one Google's this up its quite common for a lot of folks so its not just moi. Again appreciate everyone who has hardly anything to work with but finally I got the KB number. Cheers mates
I doubt it is an ISP issue. KB5019959 is the 22H2 OS build upgrade. Sometimes these things roll out in waves, depending on geographic location, phase of the moon, or the mood of some perverse MS employee. Maybe they are not yet ready to let you have it. You might be able to download a 22H2 iso, and do an in-place upgrade.
