WinRE update KB5098815 fails to install (Win10 22H2 w/ ESU)

This is the fourth time in less than one year that I’ve had trouble installing a WinRE update. I am most definitely cursed.


A quick rundown, because I don’t know what might be relevant info at this point:

Last August, I re-imaged my system drive using Acronis True Image, which nuked my original recovery partition; after manually recreating it, a couple WinRE updates refused to install, until Ramesh Srinivasan kindly helped me get them working.

Then in January, WinRE security update KB5068164 refused to install due to insufficient free space in the recovery partition. Ramesh walked me through expanding and updating it manually – my thanks again.

Then in April, WinRE update KB5087371 refused to install. The site’s AI answer suggested that a WinRE image that had been manually updated (as was the case with mine) can cause the update to fail, and that my WinRE image version indicated the update wasn’t necessary anyway, and that if I ignored the update a subsequent Windows cumulative update would remove it from the update queue, which it did. I figured things might finally be settled.


Well, another WinRE update is here, and guess what’s back? This time it’s WinRE update KB5098815, and once again it’s failing to install with an unspecified error. Out of an abundance of caution, I went ahead and doubled the recovery partition size to 2 GB (using the instructions in this guide), just to make extremely sure it isn’t failing to update due to insufficient space, but it is still failing. (I also used this other guide to solve the “Windows RE image was not found” error I received when trying to re-enable WinRE after following the first guide.)

(I’d provide a link to a ZIP archive containing my System32\Recovery files, but the last time I added that to a post in a previous thread the site’s daft filters kept auto-deleting my post, and I don’t wanna risk being forced to retype this whole post again.)

Once more, any assistance would be really appreciated. I would especially love it if we can make it so that WinRE updates normally via Windows Update once and for all.

After copying winre.wim and enabling Windows RE, run:

dism /Get-WimInfo /WimFile:\\?\GLOBALROOT\device\harddisk2\partition4\Recovery\WindowsRE\winre.wim /index:1

    Is there a way to reliably download an updated winre.wim (like the ones you uploaded)?

    You can copy the latest Winre.wim from your laptop. But, the laptop's WinRE must be fixed first. We can resize the Recovery partition on that system or more winre.wim to the C drive. Please start a new thread for that system.

    Glad that helped.

    Now, given that my PC seems unable to update WinRE by itself, I have no problem with manually applying an updated winre.wim image by following the steps you’ve provided here. My question: Is there a way to reliably download an updated winre.wim (like the ones you uploaded)?

    Chances are a filter driver is preventing the mounting of WIM files on your system. Veracrypt adds some filter drivers.

    You may also try a repair install using the Windows 10 Media Creation Tool.

    Note:

    Windows 10 ESU support end in October 2026. There won't be any more updates. Until then, you may simply follow the Winre.wim copy workaround after every update is released.

    Update:

    I found that, unlike the earlier WinRE updates, the June 2026 WinRE update strictly requires 250 MB of free space. If it's less, the update is not offered.

    Here's the latest → Winre.wim.

    On the subject computer, run:

    reagentc /disable
    
    del /a C:\Windows\System32\Recovery\Winre.wim
    

    Now, copy the downloaded Winre.wim to C:\Windows\System32\Recovery.

    Run:

    reagentc /enable
    
    reagentc /info
    ``

    On the subject PC, run:

    reagentc /disable
    
    dir c:\windows\system32\recovery /a
    

    Post the output.
