Some local governments and businesses are continuing to use the Windows 2000 operating system despite Microsoft Corp. ending its support in mid-July, arousing concern about the security of their servers and personal computers, sources said Thursday.
The software is believed to be still running on some 130,000 servers and 500,000 PCs, officials at the Japanese unit of the U.S. software giant said.
The internal affairs ministry told prefectural governments in writing in late July to immediately upgrade their operating system following the expiry of support for Windows 2000.
