Using Windows 11’s memory compression feature, you can get your PC’s RAM to store more data than its original capacity. This allows your PC to read data faster, improving your overall experience. We’ll show you how to enable and disable memory compression on your computer.

What Is Memory Compression in Windows 11?

Memory compression, as the name suggests, is a feature that compresses the memory to be loaded on your RAM, allowing your RAM to store more data than it normally would. For example, if your PC has 8 GB of RAM available, and there’s 9 GB of data to be stored on it, memory compression will try to compress that extra data so it fits within the 8 GB capacity of your RAM. If you don’t use memory compression, your PC will store the extra data in a file on your hard drive storage.

This reduces your PC’s performance as your PC takes more time to read data from a file on the hard drive than from RAM. Unless you have a specific reason, it’s a good idea to keep memory compression enabled on your system.
