Once a user logs in, Windows will enumerate the PCI devices connected to the host plug PCI ports. Every time the user locks the machine, DMA will be blocked on hot plug PCI ports with no children devices until the user logs in again. Devices which were already enumerated when the machine was unlocked will continue to function until unplugged. This policy setting is only enforced when [BitLocker Device Encryption](/windows/security/information-protection/bitlocker/bitlocker-device-encryption-overview-windows-10#bitlocker-device-encryption) is enabled. Most restricted value is 0. **Description framework properties**: | Property name | Property value | |:--|:--| | Format | `int` | | Access Type | Add, Delete, Get, Replace | | Default Value | 1 | **Allowed values**: | Value | Description | |:--|:--| | 0 | Not allowed. | | 1 (Default) | Allowed. | ## LegacySelectiveWipeID | Scope | Editions | Applicable OS | |:--|:--|:--| | ✅ Device
