What an obscene memory and CPU hog this can be. I’ve seen it grow to 3.2 Gb of RAM on one of my servers.
As it is used for Windows Updates, I stop the related Windows Services and mark them as manual to avoid this issue.
The services to stop/set to manual are:
“Windows Installer Modules Installer”
“Windows Update”
Sure, I have to manually update but I want that on my servers.
