Since I upgraded from Windows 7 to Windows 10 on my Dell Inspiron laptop back in August 2015, the following cycle has been repeating itself. The System file starts off using a reasonable amount of memory (just a few MB), then over a period of a week it grows larger and larger (300+ MB) until it slows my system to a crawl (92%+ of memory in use, writing constantly to disk), and finally I get a blue screen or everything freezes and I have to force close my laptop. Then Windows downloads some update and upon restart the System file is back down to a few MB of memory. At first I thought it was a conflict with my McAfee antivirus app, so I removed it and now use only the Windows Defender. That only helped for a few days. I have done repeated malware scans and not found any malware. I had already read the post referred to by magicandre1981 about the System file using too much memory, and followed the only advice I could discern from that post, which was to disable the the Prefetch. I disabled the Prefetch, but that didn't help at all (so I re-enabled it). I've tried using the Windows Driver kit to identify and replace drivers, but that hasn't solved the problem either. Here is a link to the current image of the Task Manager:
As you can see, the System file is currently at more than 220 MB, driving my overall memory usage to around 73% of the 4.0 GB available. Only yesterday the System file was around 100 MB, and two days ago around 50 MB. By tomorrow it will be around 350 MB and overall memory usage up to 90%, then by the next day it will be up over 500 MB and all systems will be very slow because of constant exchange of memory with the hard drive. Then the next day it will be so huge that my laptop crashes.
Let me make the problem very clear: the memory usage and size of the System file keeps growing larger and Larger and LARGER until it crashes my laptop. It is NOT a matter of the System file simply being large, but that it grows like a cancer until it is so huge that it freezes my system and I get a blue screen, then Windows downloads some update and the System file is back down to a very small size, but gradually grows again, repeating the same cycle over and over.
I would appreciate a solution that actually works, other than buying a new laptop.
