Generally speaking it doesn't matter on which drive letter the page file is, the disk performance of the drive where the page file is located is much more relevant. So, if drive P has a faster disk than drive C, then putting it on the P drive would actually be good.

I believe there are some benefits to having a page file on the C drive when it comes to crash dumps, but in most cases it doesn't matter.

Hi,

The general rule of thumb is that your page file should be at least 1.5X the size of your physical ram, or logical ram assigned to it if it's a VM.

Cheers

If this is a server, I would always move the page file to a different drive other than C:\, the page file is used when you are running log on RAM, so the page file acts as virtual RAM, but its really slow because it's using the hard drive as RAM since the physical RAM is over extended.  if this is a server, I would suggest leaving the page file on a separate drive. also another issue with the page file is that it takes up your drive space, so if you don't hard set it, the page file size will grow and consume disk space. Leave it on a different drive and hard set it with the 1.5X size of your physical RAM the way @dfke suggested. that is a far better option. set at 400MB is not worth it.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

where should I find out C Drive is set for 400 MB of RAM usage?

in the run box type the following:
 sysdm.cpl

A new dialog box will open and select the Advanced tab > under performance select settings > new window select Advanced > you will see virtual memory

The screenshot shows that C: is not the page file drive and not paging, while P: is the paging file. I wouldn't change anything.
I personally would set C: to "No Paging"

This would require a reboot so be careful if you decide to do that.

but it says C Drive is set for 400 MB of RAM usage.

No need to change. It's cleaner and clearer to understand when you look at it, thats all. That is why I would set it that way, but your screenshot shows paging on P:
