IT deployment: Custody Note for Windows

By Robert Cashman, Solicitor. Published 24 September 2026. Updated 5 October 2026.

Criminal defence solicitor in England and Wales. General guidance on police station work. It isn't legal advice.

For IT administrators at criminal defence firms who deploy software centrally, because staff can't install from the consumer Microsoft Store themselves.

Custody Note for Windows is distributed through the Microsoft Store (UK listing). This page sets out the deployment options for IT teams. It doesn't replace your firm's own security review or Microsoft's official documentation.

The public Store listing currently targets the UK region (gl=GB). A PC set to another Microsoft account region may not see Custody Note in the consumer Store. If so, use the direct Windows installer on the Download page when the Store is unavailable.

Microsoft Store listing

Store app name: Custody Note for Windows
Store ID (package identifier): 9NFSRVT3T45V
Public listing (UK): Custody Note for Windows on apps.microsoft.com (hl=en-GB, gl=GB)

Deploy with winget (Microsoft Store source)

On a managed or admin workstation, you can install from the Microsoft Store catalogue using Windows Package Manager. The --source msstore flag pulls the package from the Store. Updates then come through the Microsoft Store's own update mechanism for Store apps. Microsoft's winget and Store documentation covers the detail for your version of Windows.

winget install --id 9NFSRVT3T45V --source msstore --accept-package-agreements --accept-source-agreements

Deploy with Microsoft Intune

Microsoft documents adding Store apps in Intune under Microsoft Store app (new). Typical steps:

In the Microsoft Intune admin center, go to Apps, then All apps, then Create.
Select app type Microsoft Store app (new) under Store apps.
Search the Microsoft Store for Custody Note for Windows or store app ID 9NFSRVT3T45V (Intune supports search by store app ID per Microsoft's docs).
Configure assignments (required, available, or uninstall) to your user or device groups.
Set Install behavior (System or User) to whatever the package supports. Microsoft notes that some apps only support one context, and that Microsoft Entra registered devices may need system context for some assignments.

Official reference: Add Microsoft Store apps to Microsoft Intune. Intune can keep Store apps updated when new versions are published, subject to your policies and the app type (Microsoft documents separate behaviour for UWP and Win32 Store apps).

When the Store is blocked for end users

Plenty of firms lock down the consumer Microsoft Store on solicitors' laptops but still deploy approved apps centrally. According to Microsoft's Intune documentation for Store apps, the policy Turn off the Store application blocks end users from installing arbitrary apps from the Store app and from using the Store to install manual updates, but does not affect Intune's ability to install Microsoft Store apps via the Microsoft Store app (new) integration. Microsoft also notes that winget.exe isn't affected by the same policy. What actually happens depends on the full set of Store, App Installer and update policies you apply, so test it with a pilot group before you roll it out across the firm.

Fallbacks if Store apps aren't permitted

If your firm can't deploy Microsoft Store packages at all, there's a direct Windows installer on our Download page. It isn't code-signed, so SmartScreen may warn your users.

Can't use the Microsoft Store? Download the installer directly (Download page). This is the direct Setup.exe from our published GitHub releases, for setups that block the Store completely.
Windows may show a SmartScreen warning ("Windows protected your PC") when you run the direct installer. You can avoid it by getting Custody Note from the Microsoft Store instead. If you do use the installer, click More info, then Run anyway.
Mac users: Custody Note for Mac is a notarised direct .dmg (Apple Silicon and Intel). It isn't on the Mac App Store or the Microsoft Store. See Mac download on the Download page.

Data and security (summary)

Custody Note works offline. Attendance data is stored in an encrypted local database on the device (AES-256-GCM). Paid licences add encrypted cross-device sync (which stores a licence-key-protected copy of the database key with us) and optional encrypted cloud backup in AWS London. The app connects to custodynote.com (licensing, sync, backup, postcode lookup), GitHub Releases (updates for the direct installer), GOV.UK (bank holiday dates) and, only if a user enables those integrations, QuickFile and OpenAI.
