The percentage available isn't too relevant because Windows will initially set a small page file size and only increase it if needed, so the percentage may always reflect a relatively high number.
I would caution against setting a small maximum size to your page file size, especially
if your issue is being caused by running into your commit limit. If that's what is happening, then you're simply going to run out sooner with it capped to a lower amount.
Generally, Windows will start displaying "Windows is low on memory" notifications if you start coming too close to the commit limit (and it can't grow it). If you're not seeing those, then your issue probably isn't with the page file and you probably shouldn't go messing with additional variables. You need to find out why it's freezing.
Also, the HwInfo64 screenshot doesn't really disclose anything. The memory page of the performance tab in Task Manager would be a bit better, and an accompanying screenshot of resource monitor in the memory tab sorted by "commit" would be even better. These need to be screenshots during the time of the issue, not any other time.
i have the exact same problem since around two weeks (last cumulative windows update)
this is my pagefile while doing literally anything with a today installed clean installation of windows 11 pro.
As mentioned in the last part of my statement before the quote, more information is needed as this doesn't tell much.
All I can see is that you're using ~18.5 GB of RAM (so this seems not to be a "nothing is going on" moment) and the commit charge is ~37.5 GB. That in itself isn't a problem (some workloads do have much higher allocation than you'll be using in memory, which is the precise reason why setting a small, fixed page file size is ill advised), but if you're not seeing "Windows is low on memory" notifications then you're not having a problem. A high percentage in and of itself isn't a problem, but I wouldn't expect it so high on a PC with 32 GB of RAM if you're not "doing anything".
A recent install of Windows might mean it's doing updates or other background stuff that a new installation might be doing. Try restarting the PC (not shut down) and see if it clears it.
However, if this commit keeps growing and you eventually do get such notifications (even while doing nothing), then you may have a memory leak and would need to dive into other applications like RAMMap or Process Explorer to find out what it is.
