Here's a reminder that people on this sub don't understand what the fuck RAM is for and to not listen to them.

Unless your RAM usage is almost maxed out, there is no reason to restart. Just close your unused apps. Windows is specifically designed to keep your most used apps in RAM for quick/fast startup and switching between them, and having more RAM being used is not a bad thing as it makes your system faster overall.

Windows will also use more RAM if you have more RAM. So a PC with 8GB of RAM might have 2-4GB allocated to running Windows, a 16GB PC might have 6-8GB used, 32GB might have 8-12GB, etc. The higher the RAM usage, the better your PC will run overall.

except that most of the ram used by op is the mystery ram that is unaccounted for in  task manager
