Windows 7 Starter is the introductory edition of Windows 7, it does not support Aero Glass graphics, Fast User Switching, cannot create HomeGroups (but can join them), cannot change the desktop background, supports a screen resolution of 1024 by 768 max, targeted mainly for Netbooks and budget PC's with certain processor models such as the Intel ATOM, AMD Sempron, only available in 32 bit, Windows 7 Starter is not sold as a retail license it is a OEM license that is preloaded on computers.
You can run Windows Live Mail on Windows 7 Starter. you can run office student and home also( it usually come as a trial on most netbooks).
There is not any real good reason to run Win 7 home premium on a netbook simply because the processor is not really fast enough and there is a 2 gig memory limit in the BIOS on netbooks. Home premium will slow the computer down a little bit.
The acer will use a external dvd player and has a program that will let you make a set of recovery dvd's. I made a set from my aspire netbook and then used them to reinstall the OS. I had put a game on the hd to see if it was gone after the restore(factory) and it was not on the drive anymore. I did not have to install any programs on the netbook because windows already has the software to burn dvd's.
