The data, from Israeli software solutions company SysAid, indicates that as of April 2013, six months after the official launch of Windows 8, only 0.53% of enterprise computers running Windows OS were running on Windows 8.

By comparison, six months after the official launch of Windows 7, stastics indicated that 11.3% of enterprise computers running Windows OS were running Windows 7, out of the 11.68% total market share (as reported by Net Applications.)

“Statistics from Net Applications also showed in April 2013 that Windows 8 had a usage share of 3.84%, however, our IT Benchmark data demonstrates that the majority of Windows 8 implementations are by consumers and not by enterprises,” said Israel Lifshitz, Founder and Chairman of SysAid.

“While it is clear that Windows 7 was a highly anticipated release, businesses are not at all eager to adopt Windows 8. It will be interesting to see if the upcoming Windows 8.1 launch will be attractive enough to increase adoption among enterprises.”

Other IT Benchmark statistics indicate that less than 12% of SysAid customers were using the Windows 8 operating system. Moreover, among those 12% who adopted Windows 8, nearly 60% had deployed it on less than 10 % of their machines.

SysAid’s IT Performance Benchmark tool collects and analyzes IT data from more than 2,000 customer organizations around the world.

The news follows the announcement that Windows 8.1 will be a free uprade later this year. It seems Q4 can't come soon enough for Microsoft.
