Researchers have found a way to trick Windows Vista into ‘upgrading itself’, potentially saving users the cost of buying a new install version of the operating system.
On Friday, Microsoft confirmed reports circulating on the Internet since the beginning of the month that customers can successfully install an upgrade version of Vista on a computer without Windows XP or 2000 already on it, through a bit of installation ledgerdemain.
Here's how the "clean install" trick works according to ars technica:
--Boot with the Windows Vista upgrade DVD and begin the full installation process.
--Do not enter the product key when prompted, but continue on.
--Choose to do a clean install Vista, that is, fully wiping your hard drive.
--After you're done, boot into the still-unactivated copy of Vista.
--Run Windows Vista setup again, from inside Vista.
--Select upgrade, and enter your upgrade key.
--Install Vista a second time.
Essentially, Vista is fooled into upgrading itself, thus allowing customers to avoid the need to have a prior copy of Windows XP or 2000 installed on that computer. While time-consuming because of the double installation, advocates say this workaround not only allows users to do a fresh install of Vista, which they say will run more reliably, but can save some customers money. The amount depends on which flavour of Vista a customer gets.
The difference between the full and upgrade price of Vista Home Basic is $100 ($199 vs. $99). For Vista Home Premium, it is $80 ($239 vs. $159). For Vista Business, it is also $100 ($299 vs. $199). For Vista Ultimate, it is $140 ($399 vs. $259).
Microsoft is right: for most businesses as well as consumers, the workaround will prove to be irrelevant. Why? Because most larger corporations buy Vista in volume licenses, which are usually discounted off the list price. Also, the time involved in having IT staff manually installing Vista twice on each PC would more than outweigh any potential cost savings.
For consumers and small businesses, the vast majority will get Vista pre-installed when they buy a new PC. Buying a new PC without an operating system on it and then installing an upgrade version of Vista might actually cost more than buying a new Vista PC because of the low price Microsoft charges OEMs to pre-install Vista, along with other discounts that it offers.
Indeed, the type of person most likely to benefit from this workaround are power users and hobbyists who own multiple computers running Windows as well as Linux and Mac OS X. Indeed, one concrete scenario would be someone with a used PC that's just one or two years old running either Linux or OS X who decides to convert it to Vista and buys the upgrade version of the OS to do so.
Microsoft remains officially adamant. The spokeswoman noted that customers buying and installing an upgrade version of Vista onto one PC also forfeit the right to use XP on another PC, unless they own more than one full retail copy of XP.
