Yes sir, you read that right – Windows XP, none other than the venerable operating system from Microsoft. TEPCO was recently probed by Japan’s Board of Audit, which happens to be an organization that looks through the finances of Japan’s government and government agencies. The Board of Audit have shown an interest in TEPCO simply because Japan is looking to the company to fork out the relevant amount of money when it comes to cleaning up the carnage left behind by the Fukushima disaster.
It looks like the 48,000 PCs which run on Windows XP were not upgraded due to cost constraints, and upgrades might even have been deferred all the way to 2019, which certainly does not bode too well for the company taking into consideration how all official support for the operating system has ended quite some time ago.
