MS still needs to get their s**t together so far as upgrades. I always get the try again button. Eventually I upgraded from an ISO.
It been over 24 hours since this insider build had came out. So far I haven't found any difference with this & Build 16176.
How do you decript the ESD in AMD64_en-us zip I have the decypt-ESD.cmd Keep getting error (4) Need help
Experiencing a weird issue with this build - all fonts are missing in explorer. Oddly, UWP-based apps work just fine. I also reverted to the last build (16176), with similar results. Not sure what's going on with my testbed system, but I'll likely wipe out the current install and reinstall fresh to make sure the issue doesn't come back.
