Good morning. I have this dilemma on my hands at the moment, and I wish to get the advise of people who are more up-to-date on the W7 scene than I am .. ie: you guys I'm currently running Windows 7 Beta Build 7229 x64, using the Beta key provided my Microsoft which activated nicely etc. Due to various reasons (not Window's fault this time!) I'm in need of a nice fresh format. My doubt is this: Do I reinstall the current build that I know works fine (7229) or I look for a more up-to-date build? There's a lot of dodgy builds out there for download, which I do not fully trust, and the question of which key will work with what still lingers. Don't want to end up with a Windows that doesn't accept the key / doesn't activate / says it's not genuine after a couple of days etc... So my question is, should I stick to my tried and tested build, or find a more updated one? And if I look for a later version, what Builds should I be looking for what still works legally with Beta keys? I know I should wait for the Retail version and buy it in a couple of weeks, but time isn't permitting unfortunately. Eagerly awaiting your views.
