How do I change the installation date on the About page in Windows 10?

I’ve modified the InstallDate via the registry, and SystemInfo shows that the update has been applied, but the installation date on the Settings → System → About page hasn’t changed. Please advise on how to fix this.

    SystemInfo reads the raw registry value for InstallDate directly.

    Settings → System → About pulls data from different system components and cache, sometimes ignoring or not updating the registry value you modified.
