Is Windows 10 going into sleep mode after a few minutes?

Even with “High performance” selected as the power option and “Put the computer to sleep: Never”, I found my desktop still going to sleep after a few minutes of inactivity. Here’s how I fixed it:

  1. Open a command shell (or PowerShell) window with Administrative rights;
  2. From the command line,

    reg add "HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0" /v Attributes /t REG_DWORD /d 2


  3. From the Start Menu, go to “Power & Sleep” and click on “Additional power settings”;
  4. Click “Change Plan Settings” for the current power plan;
  5. Click “Change Advanced Power Settings”;
  6. Click on “Sleep”;
  7. Select the new, visible “System unattended sleep timeout” option and set its value to “0 minutes”;
  8. Restart the computer.
