IT Admin Checklist

✔️ If you’d like to speed up new user sign-ons check out the new new policies to speed up adding users.
✔️ If you need to keep your devices from auto-connecting to Wi-Fi access points then learn how to disable Wi-Fi auto recovery.
✔️ Trying to remotely troubleshoot a device, but don’t have enough room to gather logs? Try to clean up some storage space using MDM.
✔️ If you need to have more security, are planning on vending out your devices, or need to check a box for a security review, check out the security baseline.
✔️ If you use your own time server, and would like your HoloLens devices to use it as well check out how to set your own.

Policies to speed up adding users

As you scale deployment of your HoloLens devices across your enterprise, you can set up new users more quickly through these new policies that allow you to skip steps in your Out-of-Box-Experience (OOBE). There are two new areas you’ll be able to by-pass. When combined these screens allow for someone adding a new Azure AD user to a device to be up and running faster than before. These new policies enable you to apply even more fine tuning across your device inventory.

The new policies and screens they skip are:

Policy	What’s skipped	Screenshot
Skip Calibration	The calibration run during OOBE, which can later be run via the Settings app, or when an app that uses eye tracking prompts the user to calibrate. Using: SkipCalibrationDuringSetup
Skip Training	How to open and close the Start menu, which can later be learned via the Tips app. Using: SkipTrainingDuringSetup

The OMA-URI (Open Mobile Alliance Uniform Resource Identifier) of new policies:

• ./Device/Vendor/MSFT/Policy/Config/MixedReality/SkipCalibrationDuringSetup
• ./Device/Vendor/MSFT/Policy/Config/MixedReality/SkipTrainingDuringSetup
• Int value
  • 0 : Keep the experience (default)
  • 1 : Skip

For more info on how to increase your setup speed for new users, check out our guide on how to quickly set up new users.

Find this information later at Policy CSP – MixedReality.

New policy to disable NCSI passive polling

Windows Network Connectivity Status Indicator may get false positive Internet capable signal from passive polling. Which may result in unexpected Wi-Fi adapter reset when device connects to an intranet only access point. Enabling this policy would avoid unexpected network interruptions caused by false positive NCSI passive polling.

The OMA-URI of new policies: ./Device/Vendor/MSFT/Policy/Config/MixedReality/DisallowNetworkConnectivityPassivePolling

• Bool value

Captive portal on sign-in screen, enter Wi-Fi credentials to help sign-in

Sometimes Wi-Fi connections require additional information to provide credentials to the access point. Previously users were only able to do this the first time the device was set up in OOBE, or in the Settings app once signed in. Previously, users couldn’t adjust this configuration on the sign-in screen, which was sometimes tricky to work around.

This new feature is an opt-in policy that IT Admins can enable to help with the setup of new devices in new areas or new users. When this policy is turned on it allows a captive portal on the sign-in screen, which allows a user to enter credentials to connect to the Wi-Fi access point. If enabled, sign in will implement similar logic as OOBE to display captive portal if necessary.

MixedReality/AllowCaptivePortalBeforeLogon

The OMA-URI of new policy: ./Device/Vendor/MSFT/Policy/Config/MixedReality/AllowCaptivePortalBeforeLogon

Int value

• 0: Default – Off
• 1: On

Clean up storage via MDM

Storage Sense is available on HoloLens 2 today to manage cleanup of old files. IT admins can now also configure behavior of Storage Sense on HoloLens 2 with following MDM policies:

• Storage/AllowStorageSenseGlobal
  • Sets Storage sense to be enabled on the device and will run whenever reaching low storage.
• Storage/AllowStorageSenseTemporaryFilesCleanup
  • When Storage Sense runs, it can delete the user’s temporary files that aren’t in use.
• Storage/ConfigStorageSenseCloudContentDehydrationThreshold
  • When Storage Sense runs, it can dehydrate cloud-backed content that hasn’t been opened in a certain number of days. If you enable this policy setting, you must provide the minimum number of days a cloud-backed file can remain unopened before Storage Sense dehydrates it. Supported values are: 0–365.
• Storage/ConfigStorageSenseDownloadsCleanupThreshold
  • When Storage Sense runs, it can delete files in the user’s Downloads folder if they haven’t been opened for more than a certain number of days. If you enable this policy setting, you must provide the minimum number of days a file can remain unopened before Storage Sense deletes it from the Downloads folder. Supported values are: 0-365.
• Storage/ConfigStorageSenseGlobalCadence
  • Storage Sense can automatically clean some of the user’s files to free up disk space. The following are supported options:
    • 1 – Daily
    • 7 – Weekly
    • 30 – Monthly
    • 0 – During low free disk space (Default)

Find this information later at Policy CSP – MixedReality.

Security baseline

In some cases you may want to place some stronger restrictions on your devices. Whatever your need for security, we’ve written out two security baselines that you can use to add an extra layer of security to your device fleet.

Select this link to read the security baselines.

Configure NTP client for W32 Time service

You may want to configure a different time server for your device fleet. With this update, IT admins can now configure certain aspects of NTP client with following policies. In the Settings app, the Time/Language page will show the time server after a time sync has occurred. E.g. time.windows.com or another if another value is configured via MDM policy.

Note

Reboot is required for these policies to take effect.

NtpClientEnabled

This policy setting specifies whether the Windows NTP Client is enabled.

• OMA-URI: ./Device/Vendor/MSFT/Policy/Config/MixedReality/NtpClientEnabled
• Data Type: String
• Value <enabled/>

ConfigureNtpClient

This policy setting specifies a set of parameters for controlling the Windows NTP Client. Refer to Policy CSP – ADMX_W32Time – Windows Client Management for supported configuration parameters.

Note

Please replaces the values in the example below with the desired values for your time server. Refer to this link for more details.

• OMA-URI: ./Device/Vendor/MSFT/Policy/Config/MixedReality/ConfigureNtpClient
• Data Type: String
• Value:

<enabled/><data id="W32TIME_NtpServer"
value="time.windows.com,0x9"/><data id="W32TIME_Type"

value="2"/><data id="W32TIME_ResolvePeerBackoffMinutes"
value="15"/><data id="W32TIME_ResolvePeerBackoffMaxTimes"
