Please don't say back up your files because I'm doing an in-place install, so my files will be kept.
Back up your important files anyways because if you're installing an OS (even an upgrade) you should. What happens if the file system becomes corrupt and you have to reformat the partition? What if you can't boot after the install?
I know Windows 7 has tools to fix these things, but I've experienced too much data loss under the OS to consider them useful.
lightweight.
if you mean the windows folder alone using 36GB after updates then sure it's lightweight
Also tried Linux, forget my life.
What happened, and what distro did you use?
