changing windows 8 to 7 or possible xp

my mother bought computor with windows 8 and she is used to windows xp could she change that windows for xp or maybe change to windows 7 please any help would be appreciated thanks

Installing XP on a computer designed for Windows 8 is likely to be a serious challenge and one that may eventually prove futile. One issue, but not the only one, is the probable lack of XP compatible drivers. Manufacturers find it increasingly difficult to justify the considerable effort required to create drivers for what it essentially an obsolete OS. Also understand that Microsoft support for XP will end in April 2014. That means no more security updates and that will put your computer at risk.

Windows could probably be installed with little trouble but there could be issues here as well.

In both cases you would a legal copy of he OS.

Unless there is a compelling reason to do otherwise it is best to stay with Windows 8.

Another issue with new computers being downgraded to Win XP is that XP doesn't support 4K/512e sector disks automatically like newer versions of windows. If you install XP on a 4K/512e sector disk, you may need a utility to align the partition.

Check for 4K sector disk issues on any new install of Win XP. If installing Win XP on the newer format disks, check with the disk manufacturer for guidance. For Seagate disks, you need to contact tech support and request the utility.

Once you upgrade to Win 7, you will forget about XP for the most part.
