Microsoft said supposedly pirated copies of its new Vista computer operating system "will be of limited value" to those who use them.
Microsoft responded Tuesday to reports that some Web sites have been circulating pirated copies of Vista and the Office 2007 applications suite.
But Microsoft said in a prepared statement that those pirated copies of the OS won't work for long.
"The copies available for download are not final code and users should avoid unauthorized copies which could be incomplete or tampered. This unauthorized download relies on the use of pre-RTM [release-to-manufacture]activation keys that will be blocked using Microsoft's Software Protection Platform. Consequently, these downloads will be of limited value," the statement said.
The company did not comment on reports of pirated versions of Office 2007.
