SAN FRANCISCO — Microsoft is escalating its efforts to bring the latest version of Internet Explorer to more than 700 million personal computers in an attempt to reestablish the software maker’s browser as the best way to surf the Web.

Tuesday’s release of Internet Explorer 10 is aimed at PCs running on Windows 7, the most used version of Microsoft Corp.’s flagship operating system for PCs. A preview version of Internet Explorer 10 has been available for Windows 7 machines since mid-November. The final version of Internet Explorer 10 will be automatically sent to all Windows 7 computers set up to get updates.
