This has happened to me too. I would remove things like Microsoft Family Safety, Narrator, and Xbox ID provider and they all come back once I connect to the network.

I think it might be one of those 'required' app by Windows. Reason I say is because if it doesn't install back after connecting to the net, it'll install when I run sfc /scannow or any other repair commands for Windows.

This is expected behavior. A Monthly Update will patch different Windows features to install fixes or improvements, and it can reinstall missing components which you removed.

You have two options:
1. Use NTLite's Remove reinstalls feature to clean up after the Monthly Update (every time it is applied).
2. Disable Windows Update.

NTLite can remove components from an offline image, but there is no way to edit a Monthly Update before it is applied. The CU files are protected by hashes as a security measure so you cannot separate them.
