Ever since George Romero's 1968 movie Night of the Living Dead, zombies have kept popping up in pop culture like, well, like zombies. They appear when and where they're least expected, creating fun for some, havoc and fear for others.

But what about zombie blog-posts-- old posts that we might reasonably expect to have crumbled to pixel dust by now? Aren't blog posts like doughnuts--best consumed the day they're made?  

You, the readers of the Office Blog, apparently don't think so. I combed through our blog stats recently and discovered a milling crowd of zombie posts--aged from 6 months to 5 years old--that still get lots and lots of visits.

"No surprise" category for Excel

Excel Help writers Gary Willoughby and Frederique Klitgaard have their fingers on the pulses of Excel users, and they didn't raise an eyebrow at my list. "They're pretty common questions and popular features," Gary said. For example, "Chart Pattern Fills were an issue in Excel 2007. No surprise people are looking for it," Frederique said.

These Excel classics were among the 25 most-visited posts in the past few weeks:

Outlook perennial faves

Word's most popular posts

PowerPoint greatest hits

Access oldie but goodie

Final thought: Zombies have been around long enough now that they need their own support group. For your Office app support needs, go to Office.com.
