Windows 7 keeps moving my paging file back to C drive

So I see many many threads in here about how to move a paging file to a different drive and change its size. My question is, how do you force windows to keep those settings and not set them back to default.

For about a week now I've been trying to get my paging file to stay on my HDD instead of SSD. And no, I don't really care for "just keep it on your SSD" comments - that's not the point.

What can be causing windows to reset my paging file? It doens't just happen on a reboot, it usually happens on the next day after 2-3 reboots. After I change the settings and reboot, it appears that windows keeps them for a bit.

My TMP and TEMP environment variables keep getting reset to C:\WINDOWS\TEMP as well, and I keep changing them to E:\TEMP. And on top of all that, IE will also reset Temporary Internet Files folder.

I have only one account on my PC, so it's not due to the lack of administator priviliges either.

By the way, all you'll achieve by moving those files is slow down your computer.

Perhaps. Again, I don't really care about that. It would be nice to be able to actually compare two different settings. But for right now I'm forced with just one option.

Here's how my settings look like right after I reboot:

Ok, I'll get some more quick data and will work on that diagnostic tool.

Self-build box, Windows 7 64bit on it. C drive is on SSD, it hosts UEFI system partition and the main boot partition. The other three letters are the 1 TB Samsung HDD, which used to host previous Win7 32bit in my old box - that's why there's a letter D for "system reserved". Drive E: used to be the boot partition for that version of windows.

Basically, the way I see it, the most likely cause for this strange behavior would be due to windows somehow thinking that paths for the page file, temp directory, and internet temporary files are not vaild at some point during startup. I'm going to format E: drive and perhaps change some settings in BIOS for the HDD - I think I may have it set to be hot-swappable.

I don't know if this will work for you but I had exactly the same problem.

The paging file would last on my HDDs for about two days then it was back to the SSD - C drive. Went on for months.

I gave up and because I had a heap of RAM, disabled the page file completely. Everything was fine, then after about two weeks I thought I would try again. For some reason, which defies logic, it has stayed on the HDDs. Has lasted now for about a month so I figure that it's OK.

My HDDs are running RAID 1 and I thought that may have been the cause but apparently it wasn't.

I guess this means, do away with the paging file for a week or so and then try again.

Hopefully this works for you.
