Microsoft Patch Tuesday bids adieu to Windows XP

Microsoft will no longer issue security patches for Windows XP

This month's "Patch Tuesday" includes the final round of security fixes Microsoft will issue for Windows XP, potentially leaving millions that continue to use the OS open to attack.

XP will become an easy target for attackers now that Microsoft has stopped supporting it, said Wolfgang Kandek, CTO for IT security firm Qualys. The OS will no longer receive fixes for holes that Microsoft and others might find in the OS. Moreover, attackers will be able to reverse engineer patches issued for newer versions of Windows, giving them clues to the remaining unfixed vulnerabilities in XP, Kandek said.

Microsoft has acknowledged the problem and has been pushing hard to get users onto newer versions of Windows.

"If you continue to use Windows XP now that support has ended, your computer will still work but it might become more vulnerable to security risks and viruses," it said in an advisory.

Its efforts haven't always been successful. Qualys compiled data from 6,700 companies and found that use of XP still represents a sizable portion of OSes running in the enterprise. About one-fifth of companies in finance, for instance, still use XP -- a surprisingly large number for an industry handling sensitive data.

In retail, 14 percent of PCs still run XP, and in heath care the figure is 3 percent.

Organizations may be holding off on updating for a number of reasons, Kandek said. Some didn't realize support was closing and are just now putting a migration plan in place. Others may be taking a calculated risk, saving on the cost of an upgrade and trying to minimize exposure by limiting access to the Internet and through other measures.

In addition to ending support for XP, Microsoft is no longer supporting Office 2003 or Internet Explorer 8.

The company released four security updates altogether on Tuesday. They cover 11 vulnerabilities in Windows, Internet Explorer, Microsoft Office and Microsoft Publisher. Two of the updates are marked as critical. One of those, MS14-018, fixes a number of issues with Internet Explorer. The other, MS14-017, addresses critical vulnerabilities in Microsoft Word and Office Web Apps. They include a zero day in how Office 2010 handles documents encoded in the Rich Text Format.

Even after that fix is applied, organizations might want to disable Word's ability to open RTF files, if those types of files aren't routinely used, Kandek advised.

The two other updates in April's round of patches were marked important. One of them, MS14-020, handles a vulnerability in the company's Publisher program. The other, MS14-019, covers how Windows, including XP, handles files.

Kandek also advised administrators to apply the patch Adobe issued Tuesday for a serious vulnerability in its Flash multimedia software.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
