Microsoft has taken legal action to remove a document that possibly reveals many details about the Xbox 720 from the net.

Requests to remove the 56-page file have so far been received by Scribd and – a Czech tech site.

This action by the tech giant seems to lend credence to claims that the document is indeed legitimate.

The takedown notice reads thus:

"Microsoft has received information that the domain listed above, which appears to be on servers under your control, is offering unlicensed copies of, or is engaged in other unauthorized activities relating to copyrighted works published by Microsoft.

1. Identification of copyrighted works:

Copyrighted work(s):

Copyright owner:
Microsoft Corporation

2. Copyright infringing material or activity found at the following location(s):


The file is now also inaccessible on Dropbox, which possibly marks the first time public links to a file have been restricted by the cloud storage service.

It appears that file checksums are being compared, and when Dropbox finds one that matches the Microsoft document, it refuses to share a public link. The file may still be shared between private accounts, however.

Ironically, Microsoft's own SkyDrive cloud service doesn't prevent users from sharing a public link and preview of the document.
