Hi guys, I finally bought a small laptop and t came with the Japanese version of Windows 7 x64. It is an Asus UL20A. Now, since I have an English version of Windows 7 Home Premium (32bit) with me, can I install that and put the CD Key which came with laptop to activate? Or do I have to find a special OEM disk to do this? There are few reasons why I wanna do this. 1. Although I managed to change the interface to English, it is not as good as the native English version. At some places, the fonts are too small and ugly. 2. I need to install 32bit Windows so that I can save a little bit more RAM. 3. I need to make the C drive smaller. However, I don't know how this will affect the recovery partition. Can I simply format the drive where Windows is currently installed in, and install Windows 7 in there? Will I be able to recover to the original state (if the need to do so arises) by using that partition (by pressing F9 when booting up)? Though I have the recovery disks with me, the laptop doesn't come with an optical drive. So they are useless. Recovery partition is important.
