I think I get your drift Jaycan......
By running Windows Repair on your win 7 you are in fact seeking to keep it as pristine condition as possible. By doing this you are attempting to extend its life for as long as is possible.
So, providing the database at Tweaking remains clean, (there is no reason why it wouldn't), plus the presence of mbam+, ....you would therefore have the best chance of attaining your goal.
Many more win 7 enthusiasts would do well to follow your example.
Personally, I would adopt the "hit go" approach.....but I would be sure to have a good backup before I proceeded. Ideally on an external hard drive. Something like a clone via macrium reflect. (Just to safe and sure)
Dare I say it.....eventually win 7 will go the way of win xp......maybe a disaster zone, maybe not. Depends on the reasons you have for keeping it going. Sentimental or practical. Either way I hope for the time being it works like the dream it has always been. But....when/If you are faced with putting it down........Linux. You will be in heaven once again. Why?...cause it works out of the box.

It has been said that time heals all wounds. I don't agree. The wounds remain. Time - the mind, protecting its sanity - covers them with some scar tissue and the pain lessens, but it is never gone. Rose Kennedy
