Windows 11: 22H2 · 1.0 to 25H2 · 1.0

Specifies the maximum [removed: total ]bytes in GB that Delivery Optimization is allowed to upload to Internet peers in each calendar month.[removed: The value 0 (zero) means "unlimited"; No monthly upload limit is applied if 0 is set.]

Specifies the maximum background download bandwidth that Delivery Optimization uses across all concurrent download activities as a percentage of available download bandwidth.[removed: The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for background downloads.]

Specifies if the DNS client would use the DDR protocol. The Discovery of Designated Resolvers (DDR) protocol allows Windows to move from unencrypted DNS to encrypted DNS when only the IP address of a resolver is known. If you enable this policy, the DNS client will use the DDR protocol. If you disable this policy setting, or if you do not configure this policy setting, [removed: computers][added: the DNS client] will use locally configured settings.

Specifies the maximum foreground download bandwidth that Delivery Optimization uses across all concurrent download activities as a percentage of available download bandwidth.[removed: The default value 0 (zero) means that Delivery Optimization dynamically adjusts to use the available bandwidth for foreground downloads.]

This setting controls the inclusion of [removed: Microsoft Edge ][added: app ]tabs into Alt+Tab. This can be set to show [removed: all tabs, ]the most recent [removed: 3][added: 3, 5] or [removed: 5][added: 20] tabs, or no tabs from [removed: Microsoft Edge.][added: apps.] If this is set to show "Open windows only", the whole feature will be disabled.

Specifies if the DNS client will perform name resolution over [removed: DNS over HTTPS (DoH).][added: encrypted protocols.] By default, the DNS client will do classic DNS name resolution (over UDP or [removed: TCP).][added: TCP port 53).] This setting can enhance the DNS client to use [removed: DoH protocol][added: encrypted protocols] to resolve domain names. To use this policy setting, click Enabled, and then select one of the following options from the drop-down list: Prohibit [removed: DoH: No DoH][added: encryption: no encrypted] name resolution will be performed. Allow [removed: DoH: Perform DoH queries][added: encryption: Use encrypted name resolution] if the configured [removed: DNS ]servers support it. If they don't support it, try classic name resolution. Require [removed: DoH:][added: encryption:] Allow only [removed: DoH][added: encrypted] name resolution. If there are no [removed: DoH capable ][added: configured ]DNS servers [removed: configured,][added: that handle encryption,] name resolution will fail. [added: In addition to the generic encryption policy, additional policies can be configured at the individual protocol level. For example, in order to force DoT name resolution only, a combination of "Require encryption" and "Block DoH" would be needed (vice versa to force DoH). For the example above, it is the admin's responsibility to ensure that if DoT is forced, there are valid DoT servers configured on the machine (vice versa for DoH). ]If you disable this policy setting, or if you do not configure this policy setting, [removed: computers][added: the DNS client] will use locally configured settings. DDR (Discovery of Designated Resolvers) plaintext traffic [removed: is][added: will be] allowed as it is necessary for auto-discovering [removed: DoH][added: encryption] settings.

[removed: Set this policy ][added: Specifies ]to restrict peer selection [removed: via][added: using the] selected [removed: option. Options available are: ][added: method, in addition to the DownloadMode policy. ]0 = [removed: NAT.][added: None] 1 = Subnet mask[removed: .] 2 = Local discovery [removed: (DNS-SD). The default value has changed from 0 (no restriction) to 1 (restrict to the subnet). These options apply to both Download Mode LAN (1) and Group (2).][added: (DNS-SD)]

This policy setting allows you to prevent Windows from [removed: retrieving device metadata from the Internet. ][added: downloading applications associated with device metadata. ]If you enable this policy setting, Windows does not [removed: retrieve][added: download applications associated with] device metadata for installed [removed: devices from the Internet. ][added: devices. ]This policy setting overrides the setting in the Device Installation Settings dialog box (Control Panel > System and Security > System > Advanced System Settings > Hardware tab). If you disable or do not configure this policy setting, the setting in the Device Installation Settings dialog box controls whether Windows [removed: retrieves device metadata from the Internet.][added: downloads applications associated with device metadata.]

Prevent the "accessibility" group from syncing to and from this PC. This turns off and disables the "accessibility" group on the "Windows backup" settings page in PC settings. If you enable this policy setting, the "accessibility"[removed: ,] group will not be synced. Use the option "Allow users to turn accessibility syncing on" so that syncing is turned off by default but not disabled. If you do not set or disable this setting, syncing of the "accessibility" group is on by default and configurable by the user.

This policy setting allows you to specify the type of Remote Desktop Services client access license (RDS CAL) that is required to connect to this RD Session Host server. You can use this policy setting to select one of two licensing modes: Per User or Per Device. Per User licensing mode requires that each user account connecting to this RD Session Host server have an RDS Per User CAL issued from an RD Licensing server. Per Device licensing mode requires that each device connecting to this RD Session Host server have an RDS Per Device CAL issued from an RD Licensing server. If you enable this policy setting, the Remote Desktop licensing mode that you specify is honored by the Remote Desktop license server and RD Session Host. If you disable or do not configure this policy setting, the licensing mode is not specified at the Group Policy level.[added: Note: AAD Per User mode is deprecated on Windows 11 and above.]
