Windows 10 Update Assistant: Upgrade Windows 10 to the latest version!
October 6, 2025 - If you don’t want to sit idle while the installation is performed, press Minimize and go about your business. Windows 10 Update Assistant is upgrading to Windows 10 22H2 This part of the update process can take several minutes to finish. Depending on which Windows 10 version you’re using (the older your version, the slower the process), a clean Windows 10 installation of the latest version may be somewhat faster.

  • this is not powershell

Yes that EXE does not provide any commandline ( /?, --help etc) info (thanks MSFT!)

But there are more ways to wiggle info out of an exe (he he…)

  1. process explorer (which im going to skip as it was not useful…)

.\strings64.exe .\Windows10Upgrade9252.exe > .\string.txt

Which will give you a list with a lot of… stuff, but you can parse it out for switches

Hi all,

We’re trying to roll out the Windows 10 20H2 update using our RMM tool, which doesn’t manage feature updates.

The computers are spread across many locations running different versions of Windows 10, and after much online searching, I’ve found that the simplest way is to use Powershell to download the Windows 10 update assistant ( https://go.microsoft.com/fwlink/?LinkID=799445 ) and run it silently.

It seems that whilst the actual Windows 10 setup.exe file accepts command line switches ( Windows Setup Command-Line Options | Microsoft Learn ) the upgrade assistant file “Windows10Upgrade9252.exe” has no official documentation detailing the command line switches it accepts.

It definitely accepts some switches, as there are many websites (one good is example is https://blog.solvia.ch/2020/05/28/install-windows-10-upgrade-2004-from-command-line/ ) which give the following:

Windows10Upgrade9252.exe /quietinstall /skipeula /auto upgrade

I’ve tested this and it definitely works great!

However, I’m looking for more information about what other switches the file will accept. For example, I want to prevent automatic reboot but the “/NoReboot” switch which works for the windows 10 setup.exe file, doesn’t work for the upgrade assistant. I’ve tried running “Windows10Upgrade9252.exe /?”, but that just opens the file.

I’ve been searching online but can’t find any official documentation, so I thought I’d reach out to see if anyone has more information.

Thanks in advance!

r/WindowsHelp on Reddit: Unable to update Windows 10 with Update Assistant, Installation media etc
August 6, 2025 -

I recently got a PC from my sister that she didn't need anymore as she wanted to buy a new system. Since getting the computer I noticed that it consistently stalls at around 8% when it updates then fails and restarts. I checked the OS version and the PC is still running windows 10 from 2020. I got this error code as well (0x800719e4) in Windows Update.

I tried manually downloading Windows 10 22H2 from Windows Update Assistant as well as installation media, however both failed and gave me the same message message along the lines of "Windows cannot be installed on a flash drive using setup" even though I assumed it was installing to my C: drive (I never saw an option to choose either way and don't have a USB connected to my PC currently).

I was also looking in restore point and saw I had 2 C drives with one labelled as missing? (C:) (Missing)

If anyone knows how I could go about fixing any of these issues I'd really appreciate it as it's driving me insane lol

Also some relevant PC specs not sure if I need to include anything else please let me know.

CPU: Intel i5-9400F 2.9GHz

16gb installed RAM

GPU: NVIDIA GeForce GTX 1660 Super

Windows 10 Home (Last Update 8/12/2020)

Hi u/Ayrts63 , thanks for posting to r/WindowsHelp ! Your post might be listed as pending moderation, if so, try and include as much of the following as you can to improve the likelyhood of approval. Posts with insufficient details might be removed at the moderator's discretion. Model of your computer - For example: "HP Spectre X360 14-EA0023DX" Your Windows and device specifications - You can find them by going to go to Settings > "System" > "About" What troubleshooting steps you have performed - Even sharing little things you tried (like rebooting) can help us find a better solution! Any error messages you have encountered - Those long error codes are not gibberish to us! Any screenshots or logs of the issue - You can upload screenshots other useful information in your post or comment, and use Pastebin for text (such as logs).

If everything is working without issue, then this probably is not the subreddit for you, so you should also post on a discussion focused subreddit like r/Windows . Lastly, if someone does help and resolves your issue, please don't delete your post! Someone in the future with the same issue may stumble upon this thread, and same solution may help! Good luck!

Hi u/Ayrts63 , your post seems to mention the "latest update". As there are multiple supported versions of Windows and not everyone gets every update at the same time, it's not always easy to figure out which update you are talking about. To view the status of your most recent updates, go to Settings > "Windows Update" > "Update history". I am a bot, and this action was performed automatically.

r/Windows10 on Reddit: Windows 10 is officially dead as final mainstream OS update arrives
October 14, 2025 - It’s pretty easy to do the registry method and create a new registry key AllowUpgradesWithUnsupportedTPMOrCPU (DWORD (32-bit) with value = 1) at HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. I think the automated Windows 11 Installation Assistant will still give you the same error, but after restarting you can run the iso version from that same link by mounting it and running setup.exe.
