Why can t some brands of laptops change their operating systems? FOR EXAMPLE, CHANGE WIN7 TO WIN XP

The hardware of branded and copycat notebooks is the same, and there are no differences in hardware. But what makes brand notebooks better than copycat notebooks is that they have perfect after-sales customer service and reassuring quality assurance, as well as genuine operating systems that most brand notebooks come preset. The only advantage of copycat notebooks over brand notebooks is that they are cheaper (brand notebooks with the same configuration are sold for more than 3000 yuan, and cottages are 1600).

Sorry, that's a bit of a mistake. Since brand notebooks and copycat notebooks have the same hardware aspects, brand notebooks can also change the operating system at will. But most people don't recommend changing the operating system by themselves, because brand notebooks are generally built with genuine operating systems, and the **4 yuan 1*** on the market are pirated, and they will lose the genuine customer service provided by Microsoft after changing to pirated versions, which is really not worth it.

If you want to replace the Win7 in your laptop with an XP system, it is recommended to contact the after-sales service and add a little money to replace it. Of course,If you've bought your book for a few years,,It doesn't matter if you change it yourself.,After all, the current piracy system is very advanced.,You can also**update the patch.,It's no different from the genuine.。 It's just that if you replace the genuine version with a pirated version soon after you bought it, you won't be happy to say it.

Delete the hidden partition, repartition it, and you're ready to go.

Generally, they don't charge money for it.

Depending on the blackheart of the supplier you are buying, it will generally not make you pay more.
