Windows 7 now holds a global OS market share of 17 per cent and was installed on 93 per cent of new consumer PCs as of September this year, according to web analytics company Net Applications.
Microsoft says all its OEM partners are now producing Windows 7 machines. Windows 7's predecessor, Vista, was used by only 70 per cent of OEMs a year after launch, the company said.
Windows Vista failed to impress business users, but Windows 7 has had a more favourable reception. Most of silicon.com's CIO Jury are planning to upgrade before next year while a recent poll found that one in three users is expecting to switch to Windows 7 before the end of 2010.
Windows 7 is now the fastest selling operating system in history, according to Microsoft.
