# Policy CSP - ADMX_MMC
>[!TIP]
> These are ADMX-backed policies and require a special SyncML format to enable or disable. For details, see [Understanding ADMX-backed policies](./understanding-admx-backed-policies.md).
> 
> You must specify the data type in the SyncML as <Format>chr</Format>. For an example SyncML, refer to [Enabling a policy](./understanding-admx-backed-policies.md#enabling-a-policy).
> 
> The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see [CDATA Sections](http://www.w3.org/TR/REC-xml/#sec-cdata-sect).

<!--Description-->
This policy setting permits or prohibits use of this snap-in.

If you enable this setting, the snap-in is permitted. If you disable the setting, the snap-in is prohibited.

If this setting is not configured, the setting of the "Restrict users to the explicitly permitted list of snap-ins" setting determines whether this snap-in is permitted or prohibited.

- If "Restrict users to the explicitly permitted list of snap-ins" is enabled, users cannot use any snap-in except those explicitly permitted.

To explicitly permit use of this snap-in, enable this setting. If this setting is not configured (or disabled), this snap-in is prohibited.

- If "Restrict users to the explicitly permitted list of snap-ins" is disabled or not configured, users can use any snap-in except those explicitly prohibited.

To explicitly prohibit use of this snap-in, disable this setting. If this setting is not configured (or enabled), the snap-in is permitted.

When a snap-in is prohibited, it does not appear in the Add/Remove Snap-in window in MMC. Also, when a user opens a console file that includes a prohibited snap-in, the console file opens, but the prohibited snap-in does not appear.

<!--Description-->
This policy setting prevents users from entering author mode.

This setting prevents users from opening the Microsoft Management Console (MMC) in author mode, explicitly opening console files in author mode, and opening any console files that open in author mode by default.

As a result, users cannot create console files or add or remove snap-ins. Also, because they cannot open author-mode console files, they cannot use the tools that the files contain.

This setting permits users to open MMC user-mode console files, such as those on the Administrative Tools menu in Windows 2000 Server family or Windows Server 2003 family. However, users cannot open a blank MMC console window on the Start menu. (To open the MMC, click Start, click Run, and type mmc.) Users also cannot open a blank MMC console window from a command prompt.

If you disable this setting or do not configure it, users can enter author mode and open author-mode console files.

<!--Description-->
This policy setting lets you selectively permit or prohibit the use of Microsoft Management Console (MMC) snap-ins.

- If you enable this setting, all snap-ins are prohibited, except those that you explicitly permit. Use this setting if you plan to prohibit use of most snap-ins.

To explicitly permit a snap-in, open the Restricted/Permitted snap-ins setting folder and enable the settings representing the snap-in you want to permit. If a snap-in setting in the folder is disabled or not configured, the snap-in is prohibited.

- If you disable this setting or do not configure it, all snap-ins are permitted, except those that you explicitly prohibit. Use this setting if you plan to permit use of most snap-ins.

To explicitly prohibit a snap-in, open the Restricted/Permitted snap-ins setting folder and then disable the settings representing the snap-ins you want to prohibit. If a snap-in setting in the folder is enabled or not configured, the snap-in is permitted.

When a snap-in is prohibited, it does not appear in the Add/Remove Snap-in window in MMC. Also, when a user opens a console file that includes a prohibited snap-in, the console file opens, but the prohibited snap-in does not appear.

> [!NOTE]
> If you enable this setting, and you do not enable any settings in the Restricted/Permitted snap-ins folder, users cannot use any MMC snap-ins.
