Microsoft shares its plans to dramatically reduce Windows 8 memory usage
Microsoft detailed its plans to reduce the memory footprint of Windows 8 on Friday. — The software maker wants to ship Windows 8 with the same system requirements as Windows 7. One of the ways it plans to achieve …
Context & Ripple Effects
Microsoft's disclosure that Windows 8 will dramatically cut memory usage comes in a busy stretch for the company: within days it closed the EU-approved $8.5 billion Skype acquisition, confirmed the end of Zune hardware production, and saw independent tests rank Windows Azure ahead of Amazon EC2 and Google App Engine on cloud speed.
The stated goal — shipping Windows 8 with the same system requirements as Windows 7 — matters because it signals the upgrade will be sold as something existing PC owners can run without buying new hardware, an unusual promise for a major Windows release.
First-order effects
- Owners of Windows 7-era PCs become viable Windows 8 customers without RAM upgrades, widening the addressable base for the release beyond new-machine buyers.
- OEMs can build new machines against Windows 7's memory floor rather than reserving headroom for a heavier successor OS.
Second-order effects
- Lower baseline memory needs let manufacturers shift bill-of-materials budget toward cheaper configurations, sharpening price competition against tablet-class devices at the low end.
- Rival desktop OS vendors face pressure to treat footprint as a marketed feature rather than an accepted cost of each release cycle.
Third-order effects
- If each Windows generation holds its predecessor's system requirements, the industry's upgrade economics invert: OS adoption decouples from hardware refresh cycles, weakening the historic pairing of new Windows with new PCs.
- A flat OS memory floor leaves growing physical RAM in consumer machines available to applications and browser workloads, shifting where perceived performance gains come from.
The trend: Operating system vendors are beginning to compete on memory footprint as tablets compress the hardware budgets that desktop Windows upgrades traditionally assumed.
