What Windows 2000 and XP say about Vista's schedule
Will Microsoft finish Windows Vista on schedule? That's one of the biggest questions facing the company these days. And the completion of the first Windows Vista release candidate last week creates a new opportunity to assess its chances …
Context & Ripple Effects
The question Todd Bishop poses is a repeat of the one eWEEK asked in November 2005, when Windows Vista looked out of sync with its own targets — but the ground has shifted since. The completion of RC1 last week, following the Build 5536 preview days earlier, means Vista has cleared its last major pre-release milestone, giving schedule watchers actual release-candidate data instead of roadmap promises.
The story also traveled widely on the day it published: SuperSite's 'Dark Side of RC1,' CNET's look at whether Vista will stall network traffic, and the Seattle Post-Intelligencer's report of a key Windows executive departing with release 'in sight' together frame an ecosystem reading every signal — product quality, side effects, and personnel — as evidence about the ship date.
First-order effects
- RC1 puts enterprise IT departments and PC makers into final compatibility testing mode, so Microsoft's remaining schedule risk is now measurable in bug counts rather than milestones.
- The Windows executive exit reported alongside RC1 removes experienced leadership at exactly the point where finishing discipline matters most.
Second-order effects
- If RC1 quality forces another slip past the holiday selling season, OEMs keep building XP machines through Christmas, extending XP's shelf life and squeezing the marketing window Microsoft needs for a strong Vista launch.
- Rivals in the desktop market get a defined window to pitch alternatives while buyers wait on Vista, turning Microsoft's schedule into competitors' sales calendar.
Third-order effects
- Bishop's method — benchmarking Vista against how Windows 2000 and XP actually shipped — points to a structural tension in the mega-release model: each slipped flagship raises pressure on Microsoft to favor smaller, more frequent updates over monolithic version jumps.
- Persistent schedule doubt pushes the industry's planning assumptions away from trusting announced dates, making service packs and post-launch maturity, not launch day, the real adoption trigger for enterprises.
The trend: Microsoft's Windows releases are drifting from date-driven commitments toward quality-gated shipping, with every slip strengthening the case for a faster-cadence update model.
