As an example: with ripgrep searching the entire (500 GB) C: drive for a fixed string, Task Manager reports:

  CPU: 61% 2.49 GHz
  Memory: 10.3/48.0 (21%)
  Disk 0 (C:): SSD 100%

  In use (Compressed): 10.1 GB (0 MB)
  Available: 37.7 GB
  Hardware reserved: 1.0 MB
  Committed: 8.9/48.8 GB
  Cached: 37.9 GB
  Paged pool: 2.0 GB
  Non-paged pool: 979 MB

Observe that “Available” ≅ “Cached”.

The system is a VM with 48 GB RAM and an 800 MB pagefile running Windows 11 (and lots of background processes: Emacs, Tailscale, sshd, WSL, NVIDIA and Adobe shovelware, etc.).
