Windows 11 servicing stack update - 22621.1190​

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

Known issues in this update​

Applies toSymptomWorkaround
IT adminsUsing provisioning packages on Windows 11, version 22H2 (also called Windows 11 2022 Update) might not work as expected. Windows might only be partially configured, and the Out Of Box Experience might not finish or might restart unexpectedly. Provisioning packages are .PPKG files which are used to help configure new devices for use on business or school networks. Provisioning packages which are applied during initial setup are most likely to be impacted by this issue. For more information on provisioning packages, please see Provisioning packages for Windows.

Note Provisioning Windows devices using Windows Autopilot is not affected by this issue.

Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.		If you can provision the Windows device before upgrading to Windows 11, version 22H2, this will prevent the issue.

We are presently investigating and will provide an update in an upcoming release.
IT adminsCopying large multiple gigabyte (GB) files might take longer than expected to finish on Windows 11, version 22H2. You are more likely to experience this issue copying files to Windows 11, version 22H2 from a network share via Server Message Block (SMB) but local file copy might also be affected.Windows devices used by consumers in their home or small offices are not likely to be affected by this issue.To mitigate this issue, you can use file copy tools that do not use cache manager (buffered I/O). This can be done by using the built-in command-line tools listed below:

robocopy \\someserver\someshare c:\somefolder somefile.img /J

or

xcopy \\someserver\someshare c:\somefolder /J

We are working on a resolution and will provide an update in an upcoming release.

How to get this update​

Before installing this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Install this update

Release ChannelAvailableNext Step
Windows Update or Microsoft UpdateYesGo to Settings > Update & Security > Windows Update. In the Optional updates available area, you’ll find the link to download and install the update.
Windows Update for BusinessNoNone. These changes will be included in the next security update to this channel.
Microsoft Update CatalogYesTo get the standalone package for this update, go to the Microsoft Update Catalog website.
Windows Server Update Services (WSUS)NoYou can import this update into WSUS manually. See the Microsoft Update Catalog for instructions.

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.

Just curious as to WHY you have installed every version of Windows multiple times in a 3 month time frame.

Why did it start giving this error on the first Sfc scan after clean install: "C:\WINDOWS\System32\drivers\bthmodem.sys"
Click to expand...
Have you considered that possibly this latest install has in some way gotten corrupted is why SFC is failing this time? Have you tried a clean install more than once this time using the latest iso from Microsoft? Or did you use the same iso you used in all your other installations?

Regarding driver installation whether it be with a clean install or ongoing, the following is my understanding of how it works. I hope you can make sense of my explanation. Others , please jump in and correct me if I am off base here.

This I know. OEMs do not write hardware drivers for any particular component. The component manufacturer does.

The process flow I am not exactly sure of but it goes something like this. Normally, the manufacturer of components (ie Intel, Amd, Realtek, etc) send updated drivers associated by hardware ID to MS to be added to the update catalog and to the OEMs for their use. Windows detects the hardware id and installs the latest driver for that id it has in its catalog.

It seems in the case of Huawei, their drivers are proprietary. That means they have taken the manufacturer drivers, rebranded them Huawei, & sent them to MS. Because they are proprietary, WU will not use any of the drivers the manufacturer has sent to MS, only the ones that Huawei has sent and it appears they are not sending them very often.

Other OEMs like Dell and HP maintain their own catalog of the latest drivers that they have certified for use in their devices so their customers have access to current and older drivers if they have a problem. The manufacturers have their catalog as well which are the absolute latest drivers they have released for any particular component, whether MS has gotten around to adding the updated drivers to their catalog or not.

In your case, it seems Huawei Pc Manager as well as WU uses only the proprietary drivers and ignores the manufacturer drivers. Therefore, whatever version of your bluetooth driver you are using nor are any of your other drivers are probably the latest the manufacturer has released applicable to whatever windows build you are using.

There are 644 pages of Huawei drivers listed in the update catalog. From a user perspective, one can not make heads or tails of what they are for unless one opens each one and reads the description. Individually, I went through the first 5 pages going back to 4/22. I just looked at 22H2 applicable drivers dated from 4/22-1/23. During that time frame there were ONLY updated drivers for graphics, bios, and sound for Huawei devices. (lots of bios updates) Of course, I have no way of knowing which ones apply to your laptop's hardware. During this time I saw no bluetooth drivers for ANY of Huawei devices which tells me whatever driver you are using must be older than 4/22(before 22h2).

IMO Huawei's way of using proprietary drivers is very irresponsible, especially if they are not keeping the update catalog up to date with current drivers. They are not giving users a choice or a means to use alternative drivers if something is not working correctly. Either that, or they are using old, old components in their computers because newer components are updated regularly as Windows changes. Surely, that is not the case.

I never use WU to update my drivers. I always get them either directly from my OEM or, in my case, Intel, who actually writes the drivers for my computer since all hardware in my computer other than sound is Intel hardware.

I can attempt to help you find your latest bluetooth driver from the manufacturer but I can't promise it will install if Huawei bios restricts it in some way. More than likely anything that is not a proprietary driver will install. I guess you could try to force a non-proprietary driver which may or may not work.
If you want to attempt this, please do the following:
open device manager
right click on your bluetooth,
select properties,
details tab,
Write down the value
above the value under 'property' click down arrow
select hardware Ids
write down the value
Post the info you wrote down and I'll see what I can do.

I am not using the same iso. I'm constantly redownloading. I downloaded the Media Creation Tool again this evening and did a clean install again. I found something like this. I guess it's just a windows related thing.

This evening I did a clean install with MCT again, after all the drivers and the system were updated;
I checked the version of the "bthmodem.sys" file. 10.0.22621.1 Date:7.05.2022

Then I scanned with SFC and found the error and fixed it.

When I checked the "bthmodem.sys" version again, I saw that it was 10.0.22621.608. SFC has replaced the bug with another version.

Out of curiosity, I did a cloud reset this time. When I look at the "bthmodem.sys" version again, it's 10.0.22621.1 Date:7.05.2022.

After the SFC scan found the error and fixed it, its version is updated to 10.0.22621.608.

(Cloud reset does not remove or replace device drivers with old versions, you know)

There is no change in the bluetooth version in the device manager anyway. I checked.

The interesting thing is that I do a clean install of windows every 4-5 days or cloud reset.
After my first clean installs, I scan SFC and DISM and haven't encountered any issues or errors.

I have installed 3-4 times this week, for some reason, I just started encountering this error.

I'm using google translate, forgive me if I'm wrong.

I have attached the pictures, what version do you have?

hi @erhanercan,

Of course but why may I ask? Windows Update uses the same and does it for you.
I just read your post from above. Device drivers are best left alone sometimes as they can be OEM specific.

I use Windows 10 Realtek LAN driver, because it does not limit my network speed like Windows 11 driver (to 100Mbps only).

Out of general interest, why do you clean install so often? Would it not be faster and more efficient to make an image copy after a successful install and then restore that image when needed?

    And all three of these can get windows 11 and 12 so never out of touch

Out of general interest, why do you clean install so often? Would it not be faster and more efficient to make an image copy after a successful install and then restore that image when needed?

When I see the slightest inconsistency, I reinstall the system or in major updates. I'm a little obsessed. Now I met Macrium in this forum. I will take regular images from now on. Of course I agree with you, good idea, thank you.

Yeah regular backup, I make incremental every day, with payed MR it takes some 30 seconds and is hardly noticed.
Instead of clean install, W11 like W11 have handy feature of "In place upgrade" which replaces all system files withvirgin clean ones without loosing installed programs, APPs and files. Takes a bit longer than clean install but you don't have to reinstall them. In my case for instance with over 100 applications and games that means at least a week's work to reinstall, activate and set up. with daily backup it's up to 15 minutes or so and you are back exactly as it was yesterday.

Yes,tried that. Also checked driver; Intel says it's the latest. Ran DISM-check,scan,restore then SFC, no problems reported. Just a little glitch someware, I guess. I'll keep fiddling and something might turn up.

little glitches can sometimes be fixed by a restart. To perform a full start up from cold which will reset all the hardware drivers you must use Restart, not Shut down.

@erhanercan I am more confused than ever now. I have scoured the catalog and the web and can find no Realtek Bluetooth driver version 10.0.22621.608. I have no idea where SFC is getting the driver from. Both of the device id's you listed pull up the same update catalog page you also listed.
The only reference to a Realtek driver version 10.0.22621.x was in relation to Realtek cardreader...not bluetooth...with totally different vid. So yeah. I'm very confused where the driver is coming from. If you manage to figure it out, please post your finding so I can turn my brain off.

Glad to hear that.

If you have Fast Startup enabled (which it is by default) then that may not have worked, Fast Startup is a form of hibernation and can retain 'glitches' like this one. If so, then a Restart is guaranteed to perform a full start up from cold.

OK, I wondered why you specified "restart" rather than "shut down"...thanks for the explanation. After reading the tuit I checked the startup status and fast startup is not enabled on my computer. My power options are running under a "HP recommended" plan. As this computer is on 24/7, I think I'll leave the settings as they are. Thanks for your interest and info on this issue.
