The Microsoft Band Sync app was a real desktop utility for Windows and Mac, but it is no longer a supported way to set up or sync a Band. Microsoft discontinued the Microsoft Health service and related apps on May 31, 2019. An archived installer cannot restore that cloud service, and resetting a working Band may leave it impossible to set up again.
What the Microsoft Band Sync app did
The desktop Sync utility connected a Microsoft Band or Band 2 to a computer through its USB charging cable. Historically, it could sync the Band with Microsoft Health, show device details such as battery status, and provide firmware update or restore functions. It was separate from both the Band phone companion app and the Microsoft Health app or online dashboard.
The historical Windows workflow was to install the utility, connect the Band by USB, let the program detect it, and sign in with the Microsoft account used for Microsoft Health. That describes how the app was intended to work; it is not a current, guaranteed setup procedure.

Availability by platform
| Platform or service | Historical status | Status now |
|---|---|---|
| Windows desktop Sync app | Official USB utility for syncing, updates, and restore | Microsoft’s download is no longer available; current Windows compatibility is unverified |
| Mac desktop Sync app | A Mac version was offered | No reliable current official installer or modern macOS compatibility is established |
| Phone companion app | Used for Band setup and syncing | Discontinued with Microsoft Health |
| Microsoft Health Dashboard | Cloud service for health data and analytics | Shut down May 31, 2019 |
Microsoft’s end-of-support FAQ says the Health Dashboard and related applications and services ended on May 31, 2019. The Band apps were removed from the major app stores, and Microsoft Health Dashboard data was scheduled for deletion. Cloud-dependent features are therefore not restored by installing an old desktop program.

Can you download it now?
There is no reliable current Microsoft download for the Windows Sync app. The former Microsoft Download Center listing used download ID 44579, but it is a historical reference, not a working download page. An archival catalog lists Windows version 1.3.20913.1, published in 2016, and records the Microsoft-hosted package as unavailable. The catalog is not Microsoft and does not certify a file’s safety.
Contemporary coverage confirms that a Mac version existed, but that does not establish that an official installer remains available or that it runs on current macOS or Apple silicon. Similarly, old Windows system requirements do not prove compatibility with Windows 11. The archived Windows listing gives historical support for Windows 7 SP1, Windows 8, Windows 8.1, and Windows 10; those are not modern compatibility guarantees.

If you encounter an installer on an archive or forum, treat it as untrusted unless you can verify its provenance and integrity. Risks include tampering or malware, unsupported drivers, account-credential exposure, and device or firmware damage. Even an authentic old installer cannot bring Microsoft Health back online. Do not disable operating-system security protections casually just to run it.

“Sync” can mean three different things:
- USB communication: an old program may be able to communicate with some Band functions on a particular computer, cable, and device. That is not established for current systems generally.
- Cloud sync: the original Microsoft Health service is discontinued, so the former cloud workflow is unavailable.
- Local data extraction: community tools may offer ways to retrieve some device data, but these are separate, unofficial projects with their own compatibility and security risks.
So if Windows detects a USB device, that alone does not mean the Band can sign in, complete setup, upload workouts, or restore its old dashboard data.

Important: do not reset a working Band casually
Microsoft warned that resetting a Band after the service ended could make it impossible to set up again. If your Band still works and you value its remaining on-device functions, avoid a factory reset or repeated setup attempts. First preserve any files or records already saved elsewhere, and document the device’s current state. A reset is not a safe first troubleshooting step when the official setup path is gone.
Microsoft said some standalone tracking could continue, including limited activity and sleep functions, while features requiring the phone app or Microsoft cloud would no longer work. This does not mean every Band will retain every function in every state.

What to do for common problems
- You cannot find the official installer: Microsoft’s old download is no longer available. Avoid treating a third-party archive as an official replacement.
- The Band is not detected: Check that the cable and charging contacts are clean and functioning, but remember that cable, driver, operating-system, or device faults can all prevent detection. Detection behavior has not been verified across current systems.
- The app opens but sync or sign-in fails: The discontinued backend is a likely explanation. A server or sign-in failure does not necessarily mean the Band itself is defective.
- The Band is stuck at setup: The official setup route depended on services that no longer operate. Avoid resetting it again; a reset can make setup impossible.
- You are considering a firmware update or restore: These were historical Sync app functions, but post-shutdown operation is unverified. An interrupted or incompatible firmware process could damage the device, with no official recovery path.
Recovering old workouts or health records
First look for copies that were saved before the shutdown: exported files, old phone or computer backups, local application data, screenshots, or manually saved dashboard reports. Those local copies are different from information that existed only in Microsoft Health. Microsoft said dashboard data would be deleted when the service ended; there is no basis to expect Microsoft can restore cloud-only records now.

Community discussions describe unofficial tools for extracting or exporting some Band data, but results can vary by model, operating system, and tool version. Verify the project’s source and documentation, what data it handles, whether it requires drivers or credentials, and whether the output format suits your needs. Do not treat an unofficial extractor as a way to restore Microsoft Health.
Is Microsoft Health for Windows the same app?
No. The Microsoft Band Sync app was the desktop USB utility. The phone companion app handled mobile setup and syncing. The Microsoft Health app and dashboard were part of the wider health service and cloud experience. Microsoft also promoted a Windows 10 Health app for PCs and tablets, but it was not the same thing as the USB-focused desktop Sync utility. Microsoft Phone Link is not a Band-sync replacement; it connects supported phones to Windows and does not revive Microsoft Health.
Practical recommendation
If your Band still functions, keep it charged, preserve any existing local records, and do not reset it unless you accept that it may become unusable for setup. If you need reliable current syncing, backups, or health analytics, the discontinued Band ecosystem cannot provide them; a currently supported wearable is the practical route. Archived installers and community tools are best treated as experiments for technically prepared users, not as supported fixes.
