Friday, a judge in the “Vista Capable” lawsuit against Microsoft Corporation unsealed never before presented e-mails that Hewlett-Packard Company executives had sent to Microsoft. The electronic documents showed HP execs’ utter annoyance at the fact that Microsoft certified computers using Intel's 915 graphics chipset as compatible with their 2007 operating system Windows Vista, although the chipset did not fully support Vista’s new driver model.

Senior vice president of HP's consumer business unit Richard Walker stated in one of the aforementioned e-mails, which he had sent to co-presidents-at that time-of Microsoft's platforms and services unit Jim Allchin and Kevin Johnson, that Microsoft had displayed an upsetting lack of commitment to HP as a partner. Moreover, Walker also said that the decision to certify Intel’s chipset had rendered them to lose a large amount of money.

This is not the first incident of the like that has happened during the „Vista Capable” lawsuit, since earlier this Thursday, federal judge Marsha Pechman also unsealed some letters that claimed Microsoft had become more lenient with Vista’s technical standards so as to lend a hand to computer manufactures such as Intel, which were running the 915 chipset.

Court filings of the legal action against Microsoft read that consumers were deceived by the company, rendering the latter to buy less expensive computers produced by HP competitors, because even though they did not support Vista’s full version, they were deemed capable of running the new driver model due to the more relaxed requirements. Consequently, HP lost major ground in terms of computer sales to Intel and other PC makers whose products did not properly support Windows Vista.
