Policy
Use SMB compression by default
Microsoft Windows
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows11, WindowsServer2022
This policy controls whether the SMB client uses traffic compression by default. If you enable this policy setting, the SMB client will attempt to compress traffic by default when SMB compression is enabled. If you disable or do not configure this policy setting, the SMB client will not by default attempt to compress traffic. However traffic compression may be requested by other means. See notes below. Note: This policy is combined with per-share and per-file handle properties, through which traffic compression may be requested. As well, the SMB server must support and enable compression. For example, should this policy be disabled (or not configured), the SMB client may still perform compression if an SMB server share has compression requested. If this is undesired, and one wishes to completely disable compression, configure the accompanying 'Disable SMB compression' policy instead.
