Windows holds a 93.47% share of users on Steam, but only 67.74% have upgraded to Windows 11 nearly five years after its launch, with 25.53% still using Windows 10. The adoption of Windows 11 has been hindered by the TPM 2.0 requirement and high hardware costs. Linux's share of Steam users decreased from 5% to 4.52%. Governments, including France, are considering alternatives to Windows.
