Four gigabytes (GB) or more significant is the recommended amount of RAM to run Windows 11 smoothly. If you have 4 GB or more RAM, your computer can handle most everyday tasks without any issue.  For example, 4 GB of RAM will allow you to browse the web, play light games, and use essential productivity software without lag. However, if you want to run more demanding programs or games, you will need 8 GB or more RAM. So, if you are planning on upgrading to Windows 11, make sure your computer has 4 GB or more RAM. Otherwise, you may experience some slowdown and performance issues.
