In other words, if your upgrade from a previous beta works, then great. If not, suck it up and install clean or restore 7/8.x and upgrade from that.
there are a few things here to consider, for those who are still having troubles. first, most of the trouble's that are being reported around the net are because of the previous build, not this new one. so until you sort out the previous build, you will not have a solid install of the new one. next, if your previous build will not let you sort it out, then you can do one of two things, either roll the build back to one of the earlier builds, or update with an iso. i really don't understand why so many people are fighting with windows update, when you can easily dl an iso and update it yourself? lastly, any of you having problems with your previous build can take an image of your programs and data, and then just perform a fresh install from any iso, then restore your programs and data from the image. this is soooo much easier than going through all of what i have been reading on the last ten pages or so. there are iso's out there everywhere now, so it isn't very hard to get one.
and for those who are having problems with your new build update, it seems that those are lingering problems from the last build. because i have now updated four different computers, all coming from different situations, and all of them are working flawlessly, without most of the problems i am reading reported here. so it's not the new build. it doesn't magically work for one and not another, unless there was something wrong with the other's previous build. one last note, each of the computers i updated, were on the 10147 leak before i updated them. so maybe the fact that 10147 had better settings than 10130 was a key to having a smooth, problem free upgrade. hope this helps at least some of you.
I was able to upgrade without any problem from Win 10130 to 10158 with windows update.
I see there is a 10174? is this an official preview?
As far as a free USB stick's concerned, don't hold your breath. Excerpt from the article you posted: ". . . a new report claims that the stand-alone Home and Professional versions of the OS could be sold in retail stores via a new method: USB Flash drives." What this is alluding to is that Windows may be sold on a USB flash drive by Retailers and has nothing to do with the free upgrade.
Microsoft is giving us a free upgrade to Windows 10 (we all know the specifics by now), so why would they add the cost of a flash drive and payment to (most likely) a third party company to create a few million flash drives for something that's already costing them a pretty hefty bundle. It's just not reasonable.
