I've only had this problem <10 times, but today it happened immediately after booting and running a couple updates. I ran:
Windows update - just had the usual AV definitions update
Microsoft store - no updates
Chocolatey - updated ConEmu and MKVToolnix
PortableApps - a few updates, sry I forget which, but 5-6 small utilities
LiberKey - QDir and NewFileTime updates
Problem started after WU and MSS updaters were dismissed and during Chocolatey and PA updates. Problem persists with no open installers, consoles, msiexecs, etc. None of the updated programs or updaters are running. None of the updated programs were launched. 2 desktop icons were added via Chocolatey's updates. No other changes, no updates between this boot and the previous.
Other processes/programs running: Flux, Resilio Sync, DropBox, OneDrive, Comodo FW (firewall only), EarTrumpet, Minibin, Rainmeter, Logitech Gaming Software, Realtek audio manager, VMWare services installed with their free viewer, Intel GPU services (integrated graphics driver), NVidia drivers/container services (installed GPU). Telemetry services for Nvidia and Intel disabled, no Geforce Experience installed, all displays running off the NVidia GPU.
Guess I'll uninstall and check back in 6 months. This seems to be the experience I always have with Stardock software, unfortunately.
