HOT 286: Shutting Down vs. Restarting Your Windows PC - Windows Fast Startup
Sep 27, 2026 · 24m
Summary
Host Micah Sargent answers a listener’s question about why a Windows PC shows 41 days of uptime despite nightly shutdowns. He explains that since Windows 8, "Fast Startup" hibernates the kernel instead of fully ending it, meaning only a restart truly clears the system. The episode details how to force a full shutdown via command prompt or Shift+Shutdown, and advises restarting weekly to clear memory leaks and pending updates. Sargent also notes that the NSA recommends weekly power cycles for smartphones to evict in-memory malware.
