Windows 11, version 24H2 won't install

Only by Googling bits of the error report did I come on the tool. Microsoft tightened up backend security in 24h2 so if the driver doesn't pass the test the system rolls back.

You can do this test outside the update, Google

Microsoft readiness integrity scan tool

Download the hvsci exe of choice. How to use it is online you pipe the output to a results file > old DOS command. It will tell you what has failed. You identify the driver or drivers and delete them. Reboot and try the update again. How to delete them is online. I have published it a few times on the net so you might stumble on my posts. Do save your drivers before deleting them in case you need to go back.

Same problem with a laptop dedicated to browse and view Netflix/Prime/... on a HomeCinema.
The system only has Windows11 and a browser, absolutely nothing else installed and yet, this funking update fails at 18% for a year now.

It's not up to you users, me or anyone here to do the work.
It's up to M$ to clean its mess on our machines and do what it was payed for.
Not doing it is a severance of contract by M$. Full disrespect of the customer. Simple fact.

At least, the update app must revert the update of 24H2 on all machines and wait for a working update to be released to restart the process.

Meanwhile, I'll switch to another OS.
Funk you very much, M$ !!!

The early failure at that stage will be the drivers not being compliant or virus checking software. On the first I did pick up an issue on the "journey" to quote reality TV. That was a driver with known issues picked up during the Insider phase. A nice Mr Muhammad had found it on a driver that was on my system. That version stopped migration at that point. The guy listed off release versions that were fine. I had a fine one but either not un checking the iso box, update driver now... updated mine to one that was not compatible. Hence why going mad on updating drivers isn't a good idea. Funny enough when migration to 24h2 was completed it updated the driver to the one that was not compatible with the 23h2 to 24h2. The question then is what happens when 25h2 comes out. Cross that bridge.

Two HP All in ones here with one year difference in manufacturing. Slightly different components inside and driver was never used on mine but on the other.

The root cause of all these difficulties is suppose to be Microsoft cutting back on development staff and leaving it to the Insider program to do QA. But lessons learnt need to be fed back in and acted on. Probably that which has been missing in 24h2 development. My solution on that memory integrity driver and the one that stopped me at circa 20% was in the Insider programme posts of bug fixing, not the main chit chat which just deals with standard Microsoft Windows update issues not the ones unique to the task in hand. Skilled individuals can read the error reports to sort it out or you have to train yourself up. If I was to charge my partner my old consultancy rates for sorting that one out I'd make a fortune. More cost effective to buy a new PC.

I give up. Now I don't care for this **** update.

Same problem . 68 percent is where it gets stuck. Then the damn machine restarts and Windows update says error.

I have followed almost all the methods I found online like installing from the MS upgrade tool, clearing Software distribution Folder, checking for corrupt files and repairing then through command prompt. One method pending is deleting unauthorised profiles before Installing the update . Will try that tomorrow . Oops it's already tomorrow. Been doing this **** all night . And this is April 2025 with this problem still happening.

windows needs some serious disruptive competition. An OS that can be a very high quality and reliable alternative to it. This is utter nonsense . This is just total mental agony.

At 68% that could be memory integrity. Where I was stuck for 9 weeks. Only by Googling bits of the error report did I come on the tool. Microsoft tightened up backend security in 24h2 so if the driver doesn't pass the test the system rolls back.

It was just one Adobe DVD driver that the system didn't need that was stopping installation at that point. Suspect the driver was installed as part of Adobe Lightroom. Wasn't my laptop but Lightroom was on it so I reckon it came from there. Got the partner in recovering from an open heart operation to watch it progress beyond 70%... such excitement :).

Other people on this long thread have had success with HVSCI others it wasn't their problem. Have had the thumbs up once.

All the rest of the published solution didn't touch the issue since wasn't that. It is very indeed annoying. You get to read the text and say here we go again blah blah. I ended up on each retry doing the inbuilt re-install of 23h2 since that does all the fix it stuff that people keep publishing. But that's beside the point, so stuff is needlessly published as long lists of commands when you just do an inplace restore of 23h2. Teeth grinding on those posts. Suggest you lookup that tool and see what it finds.

It's the luck of the draw. What drivers and programs installed. All the installation methods are basically the same. The ISO method is faster than the assistant if you do repeated attempts but don't run through with update drivers now, untick it. That can be a route cause. You start with the Microsoft assistant then swap to the iso. Gives better error reports that doesn't tell you much.

I installed the big 24H2 update on my computer (HP 470 G9 laptop, Windows 11 Pro).

It failed several times at first, when I tried to install it in several different ways!

Here are the different steps:

1) It originally appeared for download on Windows Update on Nov 22. I tried to download it 2 times – the download always stopped at 8%

2) It appeared again on Windows Update on Dec 15. Now the download and installation proceeded to the end – but then the installer started automatically undoing the changes made to the computer --> reverted back to v. 23H2

3) I then tried installing from the ISO file --> failed (for some reason it reported a problem with the installation language (?) --> could not select the option at all: “Keep my files and apps”

**4) The update finally went well and without any problems with this method:**💻👍👍

Windows 11 Installation Assistant

I would like to emphasize that this is one of the three official installation methods recommended by Microsoft!

Microsoft: This is the best option for installing Windows 11 on the device you’re currently using.

Note! It is important to note that in order to proceed the installation process, everyone must first pass the WindowsPCHealthCheck (which can be launched from the link at the top of the downloaded Windows 11 Installation Assistant -application window)

Windows 11 Installation Assistant doesn't even work....it won't install. It's 2025 and Microsoft is proving to be more and more garbage...My PC is less than 1 year old with 17% storage!!!!!!!!!!!!!!

I was successful in installing with these EXACT instructions:
