In addition to liquidating stock? I'd order some changes...
1. Research creation a 3D version of Virtual Earth that resembles Google Earth, but incorporates the spiffitude of the aerial photos. Begin research on a 3D CAD version of the entire world so said 3D views can be freeley rotated. This one's gonna be a b!tch. I'd oversee the project, but it's only one day; therefore, I can only order the research project started.
2. More funding, publicity, research, and product lines from the VIBE lab. Sexy stuff coming out of that area.
3. Channel9 would have more resources - Primarily people on the project. If we added a second "video guy" we could have more frequent videos, as Scoble is undoubtedly busy with tons of other stuff. Also, videos would be converted to different bitrates and possibly a Divx/AVI format. After all, DivX was spawned by a Cinepak hack, and Cinepak is a MSFT codec. Also, the C9 homepage would have one-click links to Videos, Techoff and Coffeehouse. Mouseovering a menu item consumes valuable seconds, and I'm always tempted to click 'forums' or 'media' and get redirected to yet another gateway page. Sigh. Also, in addition to Coffeehouse and Techoff (i.e., general chat and advanced coding stuff), there would be a new forum section added for
beginning .NET programming. Not quite the highly technical discussion of TechOff, but not really the archaic miscellanea that is the Coffeehouse

4. All downloads from Microsoft will be available via download stub as well as redistributable. IE7 would have a download auto-resume feature, rather than deleting aborted downloads. This would work hopefully even better than bite-size file chunks. Genuine Windows Check will go away, since pirates need support too. All files will be available via FTP.
5. All areas of all Microsoft domains will be scripted with RSS feeds. They will not be called "webfeeds", as this is a marketing euphamism and a distortion of a term we already know. The orange feed icon button discussed in the MSN blog can stay, but it must be accompanied by the term "RSS" so people know what the hell that icon means. Download areas will also be RSS-enabled.
6. Companies to buy, in no particular order:
- Yahoo!
- AOL (not TW; buy AOL from them)
- Symantec
You might ask, "how would you do all that in a day?". Well, that's what we call
delegating authority. My lackeys will do the dirty work; that's why I'm on top.
[EDIT]: Oh yes, and I'd have pictures of my nice mountain-embedded house made into motivational posters for any employees with stock options.
