You can always do a repair if you want. Sometimes it just might have to be coaxed along.
Technically, the Windows directory is fresh. Just that some elements of the non-Windows directories might still have issues. (sarcasm)
That is why I suggest reinstall then image the drive. Deploying next time is much much easier and faster. You are not spending a day or two setting the install back up. From hours to minutes is worth the time and cost.
Having a base install with the applications that you know for sure you use and want. Motherboard drivers and base updates are also easy to have ready to go. It will greatly improve reinstalling the system. Like defrag software and other honestly handy tools. Games and such are highly optional. Since, like mysefl, I do not consider a game as essential. Some might though. So applying what you want prior to imaging will leave you with something that is more desirable then a blank slate of a Windows install.
Most imaging software can archinve to a drive or disc. So you have a few options. If you get hosed and need or are forced to reload. You know what to epxect and how long your going to be taking. Some imaging software allows to to do partial imaging updating selected parts of the install. Which speeds things up even more.
For example, If I was to relaod right now. I know I would be back in 40 minutes, tops. Posting and ready to do whatever I have to do. Even if it is benchining. Yes, I do have a bench image too. It is just the minimal to get a banch enviroment going and ready for showing off my aging machine. Once done, I can revert back to prior to the profile for benching was used. Though, I rarley bench anymore or care to.
It is just an example of how using imaging can greatly improve the reinstall proccess. you can just keep a nice speedy install going, and if goes nuts. It is actually faster to just reload instead of fiddling with wondering what went wrong (sometimes,) and how to fix the issue. Actuall
true installs are much further and fewer in between using imaging techniques.
Edit: Another benfit of imaging. It helps out what I call 'the nosey user'. What I mean by this. The user who checks out many programs regularly. "Hmm lets see what this application is"
If you find out after a bit, something screwed you. Just reload, not reinstall. It is like restore on 'roids.
