Tens of thousands of federal workers are prohibited from upgrading to the latest versions, according to memos seen by InformationWeek
In a memo to his staff, the DOT's CIO Daniel Mintz says he has placed "an indefinite moratorium" on the upgrades as "there appears to be no compelling technical or business case for upgrading to these new Microsoft software products. Furthermore, there appears to be specific reasons not to upgrade."
That will cut some tens of thousands of Vista installs.
