Learn what features of Vista will be disabled if the software isn't genuine
Microsoft's hard work to combat software piracy will be stronger near Windows Vista than they are near XP. Microsoft Software Protection Platform, the Vista equivalent of Windows Genuine Advantage, will virtually disable your computer if your Vista install doesn't outdo Microsoft's validation exam.
Exactly what happen when Microsoft determines that a copy of Vista isn't authentic isn't entirely clear surrounded by the white broadsheet describing the Sotware Protection Platform (SPP) tools. At one point, Microsoft writes that culture using a one-time copy of Vista will not lose access to their personal notes.
Instead, they will see a obstinate message on the desktop recounting them the copy of Vista isn't legal and they will lose access to faultless Vista features including:
· Windows Aero
· Windows Defender
· Windows ReadyBoost
· Download Center, Windows Updates, and other updates and brand new releases
While a unrelenting message and missing features would be a deterent to piracy, in attendance is the potential that SPP could do much more to disable a copy of Vista that fail validation. If validation fail, Microsoft writes that Vista will enter "reduced functionality mode". Once contained by reduced functionality mode, users will lone know how to use the failure to pay Web browser for an hour at a time. No other applications will be available, as within will be no Start menu or desktop icon. After using the Web browser for one hour, Vista will log the user rotten minus restrictive. The user can log hindmost on right away, but matching limitations apply. Since the eyeshade shot provided contained by the white daily say that access your computer near reduced functionality will "also allow you to buy a product push button online", it appears that the purpose of reduced functionality mode is little more than to provide a track for users of presumed pirated software to purchase another copy from Microsoft.
Exactly what happen when a Vista copy fail validation isn't clear from Microsoft's white daily or press release. Based on the spin Microsoft have put on their pains to prevent piracy of Windows XP, we'll probably own to hang around for stories of "false positives" to determine exactly what features (or core functionality) is lost when Vista fail validation.
