Before I do the upgrade on my OEM Win 7 Starter using one of the SLP keys I would like to know: Is it totally safe. Do I need to turn off automatic update? Is there any way that it can be detected as not legit? Can I use MS security essentials and still be safe? It sounds easy and simple to do but I'm a little leery about having my PC's OS being turned off/blacklisted. Thx to anyone who responds.
