Windows 10 Intermittent Hang after Login - System App Only

Potential Causes and Solutions​

1. Windows Shell Experience Issues:
   • The delay in responsiveness of system apps like the taskbar, Start menu, and Control-Alt-Delete interface might be related to issues with the Windows Shell Experience.
   []System File Corruption:
   • Although you have run sfc /scannow and DISM commands, intermittent issues might suggest deeper system file corruption or conflicts.
   []Driver Conflicts:
   • Even though you've updated your drivers, conflicts with system apps might still occur due to residual or incorrect driver installations.
   []Startup Programs and Services:
   • Conflicts or delays caused by startup programs and services could lead to the described intermittent freezing behavior.
   []Background Processes:
   • Background processes or scheduled tasks could be interfering with system stability shortly after login.
   []Power Management Settings:
   • Incorrect or aggressive power management settings, especially on laptops, might lead to intermittent system responsiveness.

     Step-by-Step Troubleshooting​

   []Clean Boot:
   • Perform a clean boot to rule out conflicts with startup programs and services:
     • Press Windows + R, type msconfig, and press Enter.
     • In the System Configuration window, go to the Services tab, check Hide all Microsoft services, and then click Disable all.
     • Go to the Startup tab and click Open Task Manager.
     • Disable all startup items.
     • Restart your computer and check if the issue persists.
   []Check Event Viewer:
   • Look for any critical errors or warnings in the Event Viewer that might give more clues:
     • Press Windows + X and select Event Viewer.
     • Navigate to Windows Logs > System and Windows Logs > Application.
     • Look for recurring errors or warnings around the times when the issue occurs.
   []Disable Fast Startup:
   • Fast startup can sometimes cause intermittent issues due to incomplete shutdown processes:
     • Go to Control Panel > Power Options > Choose what the power buttons do.
     • Click Change settings that are currently unavailable, then uncheck Turn on fast startup.
     • Restart your computer.
   []Update/Reinstall Graphics Drivers:
   • Sometimes, display driver issues can cause intermittent responsiveness problems.
   • Download the latest drivers from the manufacturer’s website and perform a clean installation:
     • Uninstall the current graphics drivers using Display Driver Uninstaller (DDU).
     • Install the latest drivers from the official NVidia or Intel website.
   []Check for Background Processes:
   • Ensure no background processes or scheduled tasks are causing delays:
     • Open Task Manager (Ctrl + Shift + Esc) and go to the Startup tab to disable non-essential startup items.
     • Check the Processes tab for high CPU, memory, or disk usage immediately after login.
   []Check System for Pending Updates:
   • Ensure there are no pending Windows updates that might be causing partial or incomplete installations:
     • Go to Settings > Update & Security > Windows Update.
     • Check for updates and make sure all are installed.
   []Run Performance Troubleshooter:
   • Use built-in performance and maintenance troubleshooters to identify potential issues:
     • Press Windows + R, type msdt.exe -id MaintenanceDiagnostic, and press Enter to run the Maintenance Troubleshooter.
     • Also, run the System Performance troubleshooter from Control Panel: Control Panel > Troubleshooting > System and Security > Improve performance using tools.
