seems M$ was keeping google in the dark about their little secret.
Microsoft Corp. knew of rival Google Inc.'s complaint to regulators about its desktop-search technology well before Google officially documented the issue in April.
The Wall Street Journal reported Monday that Google (GOOG) presented a white paper to the U.S. Justice Department and state attorneys general in April, which raised an antitrust complaint over the desktop-search feature in Microsoft's Vista operating system. Desktop search is a function that lets users scan the contents of their own computers.
However, a person familiar with the matter said that Microsoft (MSFT) was made aware of Google's concerns about its desktop search via a telephone call from the Justice Department in early December, shortly after the commercial launch of Vista in late November.
