Windows 11 2025-04 Cumulative Update 24H2 Fails with error "Install error - 0x800f081f"

[tomhass]

This updates and one previous fails with Install error - 0x800f081f.

I have tried:

1. Try Windows update install again - 5 times without success

2. Following some online articles to DISM and SFC /Scannow - that does not fix it either - I think scannow is missing some files it needs to do it anyway

Not tried (yet):

1. In-place recovery files or ISO (I do not think ISO is there anyway?)

2. Downloading ISO to run a repair

One online article suggesting not bothering wasting time with the above as Microsoft and/or PC manufacturer often resolve things in a few weeks and I can try update again.

I gave it a month, tried again but same old problem.

I wanted to get feedback here before I spend serious amount if time/energy on potentially unnecessary Windows repair or re-install from ISO (not sure if I ned to get ISO from HP ?? - I assume it auto-picks up if valid license etc?)

Thanks

You might want to try installing the standalone version of the update from the Microsoft update catalog website.

April 8, 2025—KB5055523 (OS Build 26100.3775) - Microsoft Support

You want the second file on the list:

Microsoft Update Catalog

Thanks Paul. I will give that a try.
