Windows 11 25H2 26200.8973.
Something keeps setting the amount of my C: drive set aside for System Protection to 2%.
I want it set to 10%.
Has anyone any idea what might be doing this on two different PCs I own

googles answer:
The culprit is a newly introduced feature in Windows 11 called "Point- in-time restore", which actively overrides and resets your classic
System Protection slider.
Why This Is Happening In your specific build of Windows 11 25H2,
Microsoft bundles a modern Point-in-time restore mechanism into the
Settings app. Even though it looks different from the legacy Control
Panel interface, both features share the exact same underlying VSS
(Volume Shadow Copy) storage pool on your C: drive.The new "Point-in-
time restore" feature has its own maximum storage slider, which defaults
to roughly 2% to 3%. Windows periodically runs a background maintenance
task that forces the VSS pool to match the modern feature's
configuration. Every time this task triggers, it silently overwrites
your 10% setting back down to its own ~2% default, unfortunately purging your older restore points along with it.
How to Fix It Permanentely.ÿ To keep your storage pool at 10%, you have
to change the setting through the modern interface so Windows stops
fighting itself.Open the Settings app (Win + I).Navigate to System > Recovery.Look for the Point-in-time restore section and select View or
edit (or click into its configuration menu).Adjust the Disk usage slider inside this menu to your preferred capacity.Once you save the change
here, the system will lock that value into the shared pool, and your
classic System Protection slider will finally stay where you want it.

System Restore should NOT be viewed as a backup scheme. It is merely an [attempt at a] recovery scheme. It might work, but not fix other
problems. It might not work (the typical result). It wastes disk
space. If you want to completely heal your drive, save image backups.
The image backups should be scheduled. Anytime user interventions is required means the image backups are often missing, or so long ago that
a restore results in severe loss of data or apps. Don't do the backups yourself. Schedule them. The granularity of those backups depends on
how much you can afford to lose, and how much storage space you have for
the image files.

Scheduled backup may be a good idea, but it requires the backup device to
be always connected to the PC. Removing the device except during backup would be better. For one thing, a virus can't infect a file on a disconnected device.

You could have a NAS that wakes up ten minutes before the backup,
and do the backup over the network.

Yes. That could work. However, I can think of a few of problems:
1. This means setting two timers. Some people will have trouble getting
this right.
2. The drive would need to be set up so your backup software can find it.
3. There's a possibility of backing up an infected system. There's less chance of destroying a good backup with a bad one if you use TWO backup devices and alternate between then.
4. What shuts down the NAS after doing backup?

Having said all that, *I* make *image* backup to alternating (on-site/ off-site) removable USB HDDs and different levels of *file level* backup
to USB memory-stick, NAS, 'the cloud' (Google Drive) and these removable
USB HDDs at different intervals (twice-daily, daily, weekly,
three-monthly). This way, I always have a disaster recovery backup
offsite and a differential backup of the most important stuff in the
cloud, so I'm protected against things like fire, theft, etc..
