Memory Compression RAM hog

Noticed recently Windows 11 in idle was taking 4.5GB instead of 3.5GB .it turned out the memory compression was using 1GB . My guess is a recent Windows update has  made this change . it was never this before . My PC has 16GB RAM . DDR4 prices have skyrocketed lately so i dont want to buy extra RAM .i have 2 RAM  slots that are populated so i d need memory swap. This is bad

    Use Task Manager (Ctrl + Shift + Esc) or Resource Monitor to see which processes are using the most memory. Look for any abnormal or unexpected resource usage.

    Run the following command as an administrator: reg add HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management /v DisableMemoryCompression /t REG_DWORD /d 1 /f) and restart.
