FuturDreamz: Tried to do that -- even tried to reinstall existing Bluetooth driver...however, Windows 7 barked about a policy violation (no details in event viewer). I'm fairly certain it was because Atheros deeply embedds itself and has an ineffective uninstaller. Wasted too much time trying to circumvent the process and ultimately decided to wipe the boot partition and install Win8 from scratch.
jerrybear: I like Win8. Easy to install and took about 5 minutes to navigate around their new UI. It has a Windows 7 look and feel under the hood -- except the start menu (I like the new start menu concept). Stock drivers are one rev back; the only driver Win8 didn't install was the X-FI sound card (I manually installed the Windows 7 x64 driver). My fingerprint scanner doesn't work and will require a paid upgrade. HP hasn't released their Win8 driver suite yet, so I'm temporarily limited to printing on my MFP. My only other comment is Win8 seems a bit sluggish. There is a noticeable, albeit slight, hesitation when working in certain programs, It appears to be a disk I/O issue. My Windows experience dropped from 6.0 (Windows 7) to 5.9 (Win8). Disk I/O was the lowest number.
