How Big is Windows 11 on a Computer

On a laptop or computer with 250 GB Local Disk C, the Windows 11 OS may take around 24 GB of space, after installation. This space entails the primary drivers required to be installed for hardware to properly function. Keep in mind that such primary drivers were already installed when Windows 11 setup was carried out. This is because it needed an Internet connection so no option was available to avoid drivers from being installed. But there is a rare chance of Windows 11 not inquiring for Internet connection and Microsoft Account during setup if it fails to recognize an Ethernet connection.

Based on computer hardware like utilities and Graphics cards, additional storage space of 1-2 GB may be occupied. This additional space is because drivers of AMD and Nvidia are huge in size. Make sure to always keep a margin of 10-20 GB extra space for apps and drivers. Therefore, you can aim for a minimum of 30-40 GB of empty space on the installation partition. When you upgrade to Windows 11, the scenario may be different since Windows stores entire data in Windows.old folder and occasionally trims the folder to adjust consequently.
