Modern CPUs handle multitasking situations by splitting processes between multiple processor cores, which work through different instruction threads simultaneously. High CPU usage while multitasking can be normal. If you’re dealing with this kind of everyday high-CPU usage situation, you should close all background programs and tabs you aren’t using, then return to Task Manager and see if the situation has changed.

Thanks!Įxperience Windows Feature Experience Pack 120.2212.4190.0 I’d appreciate some feedback as to whether this is a bug, or if there might be something I can adjust to fix the issue. I checked this behavior still exists with newest updates (see version info below) to BW and FF, but I think it’s probably been going on for months and I just finally figured out the high usage was related to BW.

The 100% utilization jumps from one CPU to another, but always pegs at least 1 CPU to 100%. In the Windows Resource Monitor I can see one of my virtual CPUs showing 100% utilization. BUT if I open a new Firefox window while logged out, usage immediately jumps back to around 16%. Once I’ve logged in, I can logout and usage does not increase. As soon as I login, CPU usage drops to 1% or less. I’m seeing high CPU usage (~16%) on Windows 10 with the Firefox Bitwarden extension, but only if I have NOT logged into my vault.
