Microsoft is updating Internet Explorer and Windows 8.x to fix security issues that have plagued the operating systems for years.

The update is available as a free download in the Mac App Store, which has an icon with a Microsoft logo and the words “Update for Windows 8.”

The software company says it has identified about 100 security issues in Internet Explorer versions 8.01.2 and 8 and 8-series.

“Internet Explorer 8 for Mac now includes a security update to fix a new vulnerability that could allow remote code execution in Internet Firefox and other Web applications,” a Microsoft spokeswoman said in a statement.

The software giant says it also has fixed “several security issues” in Internet explorer 8.2.5 for Mac.

The company says the update is also available in the Windows Store.

Microsoft’s release is the latest in a string of updates to the browser, which began rolling out in April after it released a security patch for its Windows platform.

Internet Explorer 10.x for Mac, released earlier this month, is the most recent update to Microsoft’s browser.

Internet Explorer 9.x was released in July 2015, followed by Internet Explorer 9, Internet Explorer 7, Internet Chrome and Internet Explorer 6.

The first update to Internet Explorer was released last month, and Microsoft has since released updates to Internet Essentials, Internet Ess, Internet Express, and Internet Essen.

Microsoft has been pushing updates to its browsers in a series of patches.

The updates have been rolled out in phases, but the updates have typically come out simultaneously.
