Anyone else getting weird stuttering in Explorer on Windows 11?

Intermittent delay across opening folders, scrolling, and right-clicking is more often caused by a shell extension, sync provider, thumbnail handler, or damaged Windows component than by SSD speed or RAM. Start by comparing a simple local folder with a OneDrive or network folder, and temporarily turn off the Preview pane; that separates content-related delays from Explorer-wide delays. Install current Windows updates and restart. Next perform a clean boot; if Explorer becomes smooth, re-enable non-Microsoft services and startup items in groups until the conflict returns. If right-click is the slowest action, check software that added context-menu commands. Also run a Windows Security scan, then run DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow. Test a new local user profile before considering a reset. If the clean profile and clean boot both stutter, capture the exact Windows build, affected paths, and a Feedback Hub recording so Microsoft receives performance traces
