Windows 11 Support Thread

[RedViking]

Same here, it got stuck on updating after restarting so I eventually had to turn the computer off.
I wonder why this particular update is so problematic?

Yeah I would prefer for it not to update. Who know what will be broken. Windows is good like that.

Windows 11 KB5065426 won’t install, issues in Windows 11 September 2025 Update affect some users - Windows Latest​

Windows 11 KB5065426 won’t install due to several errors, such as 0x800F0991, 0x800F0922, 0x80071A2D, 0x800F081F, and more. Additionally, we’re seeing reports of the Windows 11 September 2025 Update taking longer than usual to download (could be due to its large size) or a glitch. File sharing also appears to be affected in some cases.

I also got an install error trying to install this update, paused updates in the hope they fix this in the meantime.

I managed to successfully upgrade my dinosaur 'unsupported' Intel Core 2 Duo desktop PC from Windows 11 Enterprise 21H2 to version 22H2 last night, by downloading the 22H2 ISO & using Rufus on a USB drive. It took about 4 hours to install the upgrade, and I left it on all night to do any further updates.



When I woke up & ran Windows Update earlier this morning, there were still a few pending updates in the queue, which it is now busy downloading & installing...



Once it has done all the remaining updates for 22H2, I will then attempt to upgrade it one more time again to Windows 11 23H2 - it cannot be upgraded any further, as the Intel Core 2 Duo CPU is not compatible with Windows 11 24H2 or 25H2, due to the lack of essential instruction sets like SSE4.2 and POPCNT.

Next challenge is see if I can also upgrade my 2015 Lenovo G50-80 laptop (with an Intel i5-5200 CPU & 16GB RAM) - which originally had Windows 8.1 Pro pre-installed on it when I bought it - from Windows 10 Pro 22H2 up to Windows 11 25H2...

My desktop PC has now finally finished installing the 4 updates listed in my previous post...



and now there's only the 2025-08 Cumulative Update left to download & install...

HeHe ... Im not scared to test stuff .... so no, it's on my main PC

That looks interesting, how are they managing to do that, wouldn't MS call foul?

Nope ... there's a few "people" doing lite versions for years already ....

I'm running an i7 3770 running on 24h2. It started on Windows 7. Will go to 25h2 after it's been in the wild for a few more weeks.

My dinosaur Core 2 Duo started with Windows XP on its original 160GB SATA HDD - I then installed a 500GB HDD and set up a dual boot installation of Windows 7 - that HDD was then replaced with a 1TB HDD & Windows 8.1, which was then upgraded to Windows 10 and finally - just after it was released - I installed Windows 11 via the Insider Edition channel, when you could still upgrade Windows 10 directly without having to jump through hoops using registry hacks or 3rd party utilities such as Rufus & FlyOOBE...
