Not pro, nor against - I'm running win 8 on laptop and Win 7 on desktops.
Have not problems with win 8 (so far). Runing w/Start 8. Will probably Improve with Age - Just like my wife, just may take time.
And that is the reason for my "bit of advice".
Anyways, One bit of advice that may help. Use Windows 8 Back-up to perform an Image of your system drive. For laptop, Unless you have daul internal HDDs, this image should go to an External HDD. Eacy way to Re-install if you decied to.
The buried the tool for windows 8, See:http://winsupersite.com/windows-8/windows-8-tip-use-windows-7-system-image-backup
For windows 7 it was simply goto Control Panel, Backup and there it was on the leftland pane.
Any ways on your External HDD create two directories 1) M6_Win 8 Image and 2) M6_win 7 Image.
Windows will place the Image in the root drive of selected HDD, so You need to move into the appro. directory. (just copy the one you want to restore back to root directory prior to restoring.
