Search "Digital River Windows" and the first result will give you an article with full legal downloads of Windows 7. You can install them by burning a DVD using ImgBurn or making a bootable flash drive with WinToFlash. Once you have it installed, you can use the trial for 120 days by re-arming Windows whenever the 30-day trial runs out. You can reset the trial by typing "slmgr -rearm" in a command prompt and rebooting. You can reset the trial three times, at which point you can use an activator or buy a key.

And don't ask for keys or other things for free on TTG; it's against the rules.

ubuntu has a few different HD PVR drivers and apps as well as wine which can be used to run cross platform apps (msi,exe) you can also run a more advanced cross platform helper called lame duck.
