can i upgrade my laptop from windows xp to windows 7 ultimate?

From Vista to Windows 7, it's quite possible (you'll need to insert the CD and see if your computer can support the "Upgrade" option for that to happen). However, you cannot upgrade from Windows XP to Windows 7 without formatting your computer completely. The reason for this is that Windows 7 is built on a completely different platform compared to Windows XP. So if you're coming from Windows XP to Windows 7, it's time to backup your data before you install. Good luck!

yes friend you can upgrade.But it is not good idea.It is slow and complicated process.I prefer you to format the system and install windows 7. Windows 7 installation is more quicker than xp

When you are doing an upgrade using windows 7 cd you cannot install 64 bit windows 7 if your vista operating system currently installed is 32 bit.Otherwise n problem. If you are currently having 32 bit vista installed on your pc you have to format and use the bootable windows 7 cd to install 64bit os.

What naokokensaku said is correct. You can just upgrade to Windows 7 if you have Vista, but it can't be done that way from XP.

if your brother has vista then upgrade your xp to vista and then vista to seven
