The purpose of re-agent-c is to have an emergency boot OS when
the main OS is not available. For example, C: might be encrypted
and have some problem opening it. Or C: might need a CHKDSK to become
functional.

While some machines have reagentc enabled, the location of WinRE.wim is
on the C: partition itself. While this is used as a parking position,
if I understand how this is supposed to work, that's a less than optimal
position. Having the reagentc information in the BCD, point to a
separate Recovery Partition, is a better solution. The Recovery Partition
contains no customer files, so it's not a security issue.

The WinRE.wim occasionally needs security fixes. Presumably it has some
Secure Boot implications, which is why it needs to be patched. Hardly
any user computers are properly patched, because the users are expected
to perform maintenance operations they are totally unfamiliar with.
Just the fact yours is disabled, indicates how long a walk uphill
is ahead of you :-)

When you do a clean install today, the reagentc is typically disabled.
Maybe the file is on C: . Maybe the file isn't on C: at all. I don't
track the issue. I only repair them here, as my own special kind of
hobby.

The secret sauce, is the PushButtonReset.

Those two files need to be extracted and put in your work directory.

The destination is in the Recovery Partition ("Hidden"). It
can be assigned a drive letter using "diskpart.exe" , as one
means to traverse there. I'm only using "testdisk.exe" from
a third party, as a quick means to take a picture and avoid
the boredom of a lot of "dir /ah" hidden file reveals.

Those two work files would go over top of what is in there now.
The reason for this, is you're "resetting" the thing, and you
are convincing the OS to forget about the crap already
spread all over the place, and trust the two new items
(extracted from the 24H2 DVD) as a replacement.

To put the files in there, the last time I tried to do that
from windows, I was repulsed by the permissions. Now, I could
have made a giant mess of the thing, and beaten it senseless
with my "computer hammer", but instead I just booted up Linux
and put the files in there without a fuss. With the right file
system driver, Linux does not care about permissions. That's
why dropping the two files in there is so easy.

Now, you have to craft a command for the running OS, to get it
to pick up the new info.

https://www.tenforums.com/performance-maintenance/211034-recreate-winre-files-new-recovery-partition.html

If I assign the letter R: to the Recovery Partition (partition 4),
I can do this to have the PBR consumed and instantiated.

   REAGENTC.EXE /setreimage /path r:\Recovery\WindowsRE /logpath C:\Temp\Reagent.log

The command will convert the letter reference, to the alternate namespace.
This is the pointer you'd see in the enabled reagentc /info later.

   \\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE

You could also direct the operation, by using that identifier, instead
of using the R: trick and a diskpart letter assignment.

In the administrator window you're issuing that command, should
be confirmation it took. You were starting with reagentc disabled,
before using that command, so that the PBR is "ready-to-take". The
logic behind that stuff, has many curve balls it can throw at you.

For the OS to later be able to patch that file, on a Patch Tuesday,
you need enough space in the partition. Let's say the partition
is 600MB right now. You should at least *double* the size,
if you are planning ahead for one of its little party tricks.
What the stupid thing does, is it can move the WinRE.wim out of WindowsRE
and put it in a "nearby" folder on the same partition. If it is patching,
and it runs out of room while holding *two* of those files in its
possession, instead of copying the moribund file to the C:
recovery area, that's how it can run out of space. The documentation
says "it only needs a small increment in space, to handle updates".
Sure, that's if nothing stupid happens... :-/ Sometimes it moves
the useless file to the C: storage location, but sometimes it
moves it within Partition 4 in my example instead.

Anyway, that's a quick description of doing a PBR, with enough
detail so you can look it up for a recipe.

To resize the Recovery Partition, you can use Linux GParted for that.
Sure, Windows has plenty of little disk editing utilities, but
the Windows utils don't like the taste of some of the materials
and won't work on them. The Linux side isn't as picky. There is
just one thing the Linux won't do, and that is touch in any way,
the 16MB partition that contains no file system. Macrium knows
to use "dd.exe" to handle that partition. But other utilities
are just not prepared for "data not sitting in a file system".
Otherwise, if your Recovery Partition needs a resize, doing
it that way avoids all sorts of diskpart.exe ceremonies involving
deleting the poor partition and creating a new one from scratch.
which is a whole lot of unnecessary work, when a resize is only
a reboot away from success.

Don't forget to change the date setting on the computer,
on your return from Linux.
