Quick Answer

Click the Start button, click the Power icon, and explicitly select Restart. Do not choose Shut Down, as Fast Startup prevents a full system reset.

Summary ​

Many common computer issues—such as freezing applications, strange File Explorer behavior, or vague Outlook errors—are caused by temporary system glitches. This article explains why and how to perform a proper restart to resolve these problems.

Prerequisites ​

  • Save all open work in Word, Excel, etc.
  • Close as many applications as possible manually.

Instructions ​

1. Perform a Proper Restart ​

Shutting down and turning the power button back on is not the same as a Restart due to Windows "Fast Startup" technology. Make sure you specifically select "Restart".

  1. Click the Start button (Windows logo).
  2. Click the Power icon.
  3. Select Restart.
    • Note: Do not select "Shutdown".
  4. Wait for the computer to reboot and return to the login screen.
  5. Log in and test if the issue persists.

2. Verify System Uptime (Optional) ​

You can check how long it has been since your last full restart.

  1. Right-click the Taskbar and select Task Manager.
  2. Click the Performance tab.
  3. Look for Up time at the bottom.
    • If this says several days (e.g., 5:00:00:00), your system needed this restart!

Troubleshooting ​

DANGER

A restart fixes about 80% of daily quirks. If the issue continues immediately after a fresh restart, it may require IT support.
