What to Do When Windows Starts Slowly

Identify common reasons a PC takes too long to become usable after sign-in.

Quick Answer

Review startup apps, available storage, Windows updates, and unusually heavy processes in Task Manager.

Step by Step

  1. Save any open work before making changes that could close programs or restart Windows.
  2. Review startup apps, available storage, Windows updates, and unusually heavy processes in Task Manager.
  3. Test the result before making additional changes.
  4. If the problem remains, note any exact error message before restarting or changing more settings.

If That Doesn't Work

  • Windows menus can vary slightly by edition and update level.
  • Avoid registry edits, third-party cleanup utilities, or disabling security features for ordinary troubleshooting unless there is a specific verified reason.
