Moreover, there are other effective methods to improve PC performance on Windows 11 and get your system to work smoothly.

What is ReadyBoost?

ReadyBoost is a Windows feature introduced in Microsoft Windows Vista, then included in later versions of Windows. Its purpose is to fasten up the Windows system by using a USB drive to store cache data. Furthermore, it improves the system performance and speed of Windows without installing additional RAM on the PC. Hence, the external flash memory storage serves as an extension of your system memory.

Why is Readyboost disabled?

The ReadyBoost feature on Windows 11 may not be enabled for some reason, prompting it not to work when selected under properties. However, ReadyBoost may be disabled if your PC has enough system memory. It means there is no need to initiate an external memory for its process. Also, you can’t use ReadyBoost on an SSD, so without a USB drive or external memory, ReadyBoost will be disabled. Other reasons why ReadyBoost can be disabled are:

Incompatible USB devices – Users can experience the ReadyBoost option being disabled if the USB driver or external hard drive inserted is not supported. It won’t be usable as an extension space for the boost process. SuperFetch or SysMain service not running – The ReadyBoost feature depends on some services to function on your computer. Hence, the ReadyBoost function may be disabled on Windows 11 if they are not installed.

Other reasons may be responsible for ReadyBoost being disabled on Windows 11. Nonetheless, we’ll take you through how to enable it.
