Stroh strikes an upbeat tone. "Contrary to some of the gloomy headlines out there, our preliminary internal data paint a very different picture about update progress...." Ninety-percent of those who received the 'update available' alert had no problems; and 50% of those that did either had a flakey Internet connection, or didn't have enough disk space on their PC. For updates through Microsoft's online Zune store, the Windows Phone handset is cabled to the PC, and then creates a backup on the PC's hard drive of all data on the phone.

He uses rhetorical questions to contrast the "gloomy headlines" with a dose of realism. "Has the update process gone perfectly? No — but few large-scale software updates ever do, and the engineering team here was prepared."

Stroh acknowledges the human pain of technical problems. "Of course, when it's your phone that's having a problem — or you're the one waiting — it's still aggravating."

He assures readers that "we're committed to learning from our first update and improving the process. We know we have work to do, and we won't be satisfied until you are."

Ironically, when on the same blog on Monday, he explained that this "relatively small" update "is designed to improve the software update process itself."
