I fresh installed Windows 11 25H2 and performed a Windows Update this morning.

Immediately, I noticed Kaspersky showing c:\windows\system32\hpatchmontask.cmd as a genuine file in application management. It seems this file is related to Hot Patching, updates without restart.

Problem is that I asked a couple of friends and they both told me that they don't have this file in their <system32> folder albeit one of them is still on 23H2 with hot patching starting with 24H2.

Can anyone please confirm these files should exist in the <system32> folder:

hpatchmon.dll (152,960 bytes)
hpatchmonTask.cmd (6,795 bytes)

They are both digitally signed by Microsoft.

Thanks!

    …still on a horse.
They are in my system32 folder on two 25H2 computers [that have never been networked together].
They are digitally signed by MS.
I've no reason to think they are not genuine.

Haven't a clue, I do not work for MS.


All the best,

For every Monthly Update, MS provides an unique CSV file listing all the new or changed files included in that update.

https://go.microsoft.com/fwlink/?linkid=2334929
"hpatchmon.dll","10.0.26100.5074","05-Sep-2025","20:09","138,648"
"hpatchmonTask.cmd","Not versioned","05-Sep-2025","20:09","6,795"
"hpatchmon.dll","10.0.26100.5074","05-Sep-2025","20:32","152,960"

That's very helpful, thanks.

How do I get these CSV files, a search for "hpatchmonTask.cmd" site:microsoft.com returns just a bunch of links in Chinese.

ElevenForum News page always has an article for every Cumulative update and it includes a link to the MS article about the CU.
It is the MS article that has the list of files.

But there is no equivalent [that I have found] for new Windows Versions or ISO files.

Every W10 & 11 release gets its own Update History page, which lists the Monthly Updates in reverse order (newest updates at the top).

You can bookmark these links:
Windows 11, version 25H2 update history
Windows 11, version 24H2 update history

If you select a specific KB update from the left margin (right now 25H2 only has Sep. 2025), you get that month's KB information. Scroll all the way down the page and you'll find a section:

File information

For a list of the files provided in this update, download the file information for cumulative update 5065789.
Click to expand...

Download the CSV, and use the findstr command to search for a filename:
Code: 
> findstr /i hpatch 5065789.csv
"hpatchmon.dll","10.0.26100.6725","27-Sep-2025","04:30","141,200"
"hpatchmonTask.cmd","Not versioned","27-Sep-2025","04:30","7,210"
"hpatchmon.dll","10.0.26100.6725","27-Sep-2025","04:40","152,960"
"hpatchmonTask.cmd","Not versioned","27-Sep-2025","04:40","7,210"

Obviously it doesn't inform you where the file lives, but it reports what's the last version of the file, it's release date, and file size.
