What I most like about today’s advanced technology is support for cross-platform integration. Let me simplify it. It means we can integrate different devices and control one gadget using the other. It makes the user experience more simplistic and sophisticated at the same time. The term cross-platform denotes different operating systems. For instance, do you know you that you can unlock Windows laptop using Xiaomi’s Mi Band smartwatch.?
Sounds interesting right.? In this guide, I will explain how you can do it. Rest assured that you do not have to hack, root or modify any device to use this feature. This feature is officially supported by the Mi Band smartwatch. Recently, Xiaomi rolled out a new firmware update for the Mi Fit App. The latest upgrade with build 4.0.17 now allows the Mi Band user to unlock their Windows Laptop using the smartwatch. Let’s see how we can accomplish this.

How to Unlock Windows Laptop with Mi Band 4
First, you need to make sure that your Mi Fit App is running the 4.0.17 version. Only in this version laptop unlocking is supported. For this guide, I will be using my Mi Band 4. If you use a Mi Band 3, all the steps will work fine as well. For easy understanding, I have broken down the entire process into sections. Follow the steps carefully as the way I have put them up.
Enable Unlock Mi Notebook
- Go to the Mi Fit App [Install it from Play Store if you are a first time user]
- Tap on Profile
- In the next screen under My Devices, tap on Mi Smart Band 4
- Scroll down and look for the option Lab. Tap on it to open
- You should see the option Unlock Mi Notebook
- It should be disabled by default. Tap on the toggle beside it to enable it.

- You will see a pop-up asking to confirm the action reminding you of possible battery consumption.
- Tap on OK to continue.
Downloading the Mi Blaze App
- Open your Windows laptop [The guide is exclusively for Windows OS]
- Head over to the Microsoft Store
- You need to download the Mi Blaze Unlock App.
- There is a twist though. This app is not available for the Indian region as of now. So, you will see an unavailable message beside the app. Don’t worry. We will fix that up.
- Go to the Settings section on your laptop.
- Click on Time & Language > go to Region

- Now you need to change your Region to China [My region is India as I’m located in India. So I change the region from India to China]

- At this point close the browser if it is open. [Close all the running applications. No restart is required though]
- Refresh on the home screen [not mandatory]
- Now click on the Microsoft Store shortcut on your Taskbar
- Search for Mi Blaze Unlock
- You will observe that now the app is available for download. Click on Get

- Download it and let it install.

Note
After installing the Mi Blaze Unlock app, you can change the region back to your original region. That won’t affect the working of the app
