> The ID is generated when Windows is set up with a Microsoft Account
So not only was this “hacker” using Windows and Edge, they singed in to windows with a Microsoft account. And then used that same computer for their social media. Nice.
Edge has a feature where it will periodically pull the bookmarks and browsing history from any other browsers you have installed, so they'll then get sent to Microsoft and associated with your Microsoft account. This was initially enabled by default without the user's consent, although I believe now you may have to opt into it if you do a fresh Windows install. I only realized this was a thing because one time my work PC rebooted to install an update, then Edge came up instead of Firefox, but with all my Firefox tabs. I guess this was part of some effort to try to trick old people who wouldn't notice the difference into switching to Edge. Here's a news article about someone else running into this when it started happening: https://www.theverge.com/24054329/microsoft-edge-automatic-c...
"Old" people? How about the vast majority of the public, which is not represented on HN?
Not to mention that one of the many major UI regressions in Windows is the removal of title bars from application windows, which is fundamental to this "trick." Try opening a PDF in Edge and also in Acrobat. Neither window has a title bar, and they are otherwise almost identical. You have to scrutinize the very few controls around the window to determine which app you're looking at.

I think probably it sends the gdid back to Microsoft as part of telemetry/updates/MS account periodic re-auth, which lets them know the current IP address, and then once the government has Microsoft's logs and the various target websites' logs, they can correlate based on IP address. I don't think it's actually sending the gdid to the web sites. Maybe.
This serves to further illustrate that nobody should be using Windows for anything that involves the need for privacy. And doubly, triply, and morefold so, nobody should ever sign a Windows machine into a MS account for any reason.

The ID is generated even if you only create a local user account. I don't know to what extent that affects tracking/telemetry though.
How exactly does Microsoft link their gdid to a hotel booking?
Hotels last I saw don't collect an obscure gdid...
Did this victim use edge and sync their browser history or something perhaps?

Microsoft and its software are trash now.
There's a blurb in the article:

Edge seems likely. Its settings include:
>Send optional diagnostic data to improve Microsoft products [Includes how you use the browser, websites you visit, and enhanced error reporting. Determined by your Windows diagnostic data setting]
>Allow Microsoft to save your browsing activity including history, usage, favourites, web content, and other browsing data to personalise and improve Microsoft Edge and Microsoft services like ads, search, shopping, news, and Copilot [Includes your history, usage, favourites, web content and other browsing data]
Probably had his laptop with him and they simply traced the gdid to a specific IP address that they determined belonged to the hotel
How does the GDID compare to the UDID (Unique Device Identifier) and serial number in iOS; and the Apple Hardware UUID and serial number of Macs?
well, mostly the name. And the fact MS gave away GDID - IP mapping to the govt.
