I admit I have rather small free space available on my
C:\ drive (only 3-4 GiBs usually, with a 4 GiB pagefile being around), but what really annoys me is this:
Windows sometimes does an operation(1) which supposedly requires more free space than available and thus, it shrinks my pagefile to 600-800 MiBs (or even less) and then allocates the space on my hard drive for that certain something.
After this (here comes the annoying part), it usually complains about running out of memory when I start a memory-heavy application or videogame (which is never a problem if the 4 GiB pagefile is a 4 GiB pagefile). And because the size is already allocated, I can't quickly set the pagefile back to its original size.
In system settings, the paging area has a fixed (hey, not so fixed, it seems afterall) size of
4096 MB. Windows is not supposed to shrink it, yet it does.
I started with a 45 GB partition, now I'm at 65 and it's not enough either.
I regularly clean my computer from stale temp files and other orphan or expired stuff (such as memory profiling reports), but seemingly the disk space is leaking away. Antivirus checks are regular too, so if it is a malware, it is a brand new never known one.
(1): I think it is the shadow copying for System Rescue, which is set to have
2 GB size available. But I never ran into this issue, all I see is that there is no space (few hundred MiBs) left on the partition, and the pagefile is yet again only a few MiBs large.
I'm thinking about recycling my Linux's swap partition (I have a dual-install setup on this drive) to become a Windows pagefile.sys hosting partition when Windows is booted, and turn back to a Linux swap when Linux is booted. If you could help me out about that, I have this other question here.
