Enable or Disable USB Selective Suspend in Windows 11

USB selective suspend is the ability to power down and later resume an idle USB device while the computer to which it is attached remains in the working state (S0). For energy-efficient operation—especially on mobile PCs—all USB devices and drivers should support selective suspend. Powering down a device when it is idle, but while the system remains in the S0 state, has the following significant advantages:

  • Selective suspend saves power.
  • Selective suspend can help reduce environmental factors such as thermal load and noise.

The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers since it helps conserve battery power. Many devices, such as fingerprint readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices, when the device is not in use, reduces overall power consumption. More importantly, any device that is not selectively suspended may prevent the USB host controller from disabling its transfer schedule, which resides in system memory. Direct memory access (DMA) transfers by the host controller to the scheduler can prevent the system’s processors from entering deeper sleep states.

This tutorial will show you how to turn on or off USB selective suspend for a power plan in Windows 10 and Windows 11.

Windows updates to improve security and PC performance periodically, so it is recommend you recreate the recovery drive annually. Personal files and any apps that did not come with your PC will not be backed up.

This tutorial will show you how to create a bootable USB recovery drive that boots to advanced startup (WinRE) to troubleshoot, restore, or recover Windows 11.

Enable or Disable BitLocker to Unlock OS drive at Startup with PIN and USB in Windows 11

BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned drives and computers.

New files are automatically encrypted when you save them to a drive encrypted by BitLocker. However, if you copy these files to another drive or a different PC not encrypted by BitLocker, the files are automatically decrypted.

BitLocker checks the PC during startup for any conditions that could represent a security risk (for example, a change to the BIOS software that starts the operating system when you turn on your PC, or changes to any startup files). If a potential security risk is detected, BitLocker will lock the operating system drive and you’ll need a special BitLocker recovery key to unlock it.

BitLocker will automatically unlock a OS drive encrypted by BitLocker with TPM at startup by default in Windows 11.

You can enable the Require additional authentication at startup policy to allow BitLocker to unlock the operating system drive with a PIN or USB flash drive.

This tutorial will show you how to enable or disable BitLocker to unlock the operating system drive at startup with a PIN or USB flash drive in Windows 10 and Windows 11.
