In 2001, Microsoft and the U.S. Department of Justice reached an antitrust settlement that required Microsoft to change certain business practices, share technical information with third-party software developers, allow flexibility in configuring Windows, and submit to oversight.

The Short Version

The record supports the substance of this claim. DOJ and court documents from 2001 show the settlement required conduct changes, interoperability disclosures, OEM flexibility in how Windows presented competing middleware, and compliance oversight. The main caveat is wording: the disclosure duty covered specific interfaces and related interoperability information, not all technical information broadly.

Caveats

"Technical information" is too broad; the settlement mainly required disclosure of APIs, interfaces, and related interoperability information.
The 2001 agreement was reached that year, but some oversight and compliance details were formalized in the later court-entered Final Judgment.
The Windows-configuration flexibility primarily applied to OEM treatment of competing middleware, not unlimited redesign or removal of Windows components.
