Windows Runtime Broker is using too much memory
Runtime Broker is a Windows process in Task Manager, which helps in managing permissions on your PC for apps from Microsoft Store. It should only use a few megabytes of memory, but sometimes, a faulty app could cause Runtime Broker to use as much as a gigabyte of RAM or more. An app may be the cause of the error when your RAM use is high and the PC runs slow.
