Why does Windows 10 not display a low memory error?

A couple of months ago, I've had to move from Windows 7 to Windows 10 due to the obvious security risks of running an unsupported OS. The problem that I'm having though is that for some reason, the low memory warning isn't working. In Windows 7, I would get a low memory warning, which would tell me which programs are eating up the computer's memory. I could either:

• close those programs,

• let the system force close the programs, or

• ignore the warning - the result being that the memory hogs would be forced to close if memory usage went even higher.

In other words, it worked the way it's supposed to work, at least the way I know it from Windows in general. On this Windows 10 system, on the other hand, I get no warning at all. Instead, sometimes the programs themselves close - or the entire system bluescreens with a SYSTEM_SERVICE_EXCEPTION caused by win32kfull.sys (0x0000003b) - this happens an estimated 1 in 5 (!) cases. I've tried sfc /scannow a couple of times, but it always says that it didn't find any integrity violations. Windows is set to automatically manage the page file, so that shouldn't be a problem. What is interesting is that Windows 10 doesn't seem to be able to automatically allocate as much virtual memory as Windows 7 did. (Possibly related: when a program crashes, I don't get any error message, either. The program just silently crashes without any message box, as if I had force closed it. Could that maybe have something to do with it? I have not found a solution to that problem either) The reason I'm so certain that it's out of memory: I have Process Hacker running in the background and keep an eye on my resource usage. The crashes always occur when the computer is already using a certain amount of RAM, and I start a certain process that eats up a lot of RAM at once (that process essentially runs a bunch of instances of a certain program in parallel to use as many CPU cores as possible, but that also eats up a lot of RAM). Anyone have any idea how to restore the low memory warning in Windows 10? (maybe some registry setting isn't correct?)
