Isssue description

When explorer runs for a long time, a bunch of initially-suspended threads are created in the explorer process, and a lot of memory is consumed over time. My system has been up for almost 50 days. Explorer is nearing a gigabyte of memory usage, has hundreds of suspended threads "WorkFolderShell.dll!DllUnregisterServer+0x26a0", and has an excess number of handles for those threads and many many terminated threads. Overall, this slows down the entire desktop and file browsing experience significantly. For laptops with only 8GB ram, this makes a big difference.

Steps to reproduce

Run your system for a long time (does not need to be 50 days), notice how explorer will increase its resource usage (memory, threads, handles), and how the desktop experience slows down over time.

Expected Behavior

Resource utilization stays relatively the same when nothing demanding is being done.

Actual Behavior

Desktop experience slows down due to leaked resources.
