This policy setting allows you to control the maximum amount of disk space that can be used by Windows to save snapshots for Recall. You can set the maximum amount of disk space for snapshots to be 10, 25, 50, 75, 100, or 150 GB. When this setting is not configured, the OS configures the storage allocation for snapshots based on the device storage capacity unless the current user specifies a different value. 25 GB is allocated when the device storage capacity is 256 GB. 75 GB is allocated when the device storage capacity is 512 GB. 150 GB is allocated when the device storage capacity is 1 TB or higher. If both maximum storage duration and maximum storage space are set for Recall, then snapshots are deleted when the first maximum is reached. Important: This setting applies to Enterprise and Education client SKUs only.

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
