After I installed Windows 10 Anniversary Update (see my report) I recommended holding the update until showstopping bugs could be fixed. I specifically noted a reproducible total system crash which happened after plugging Kindle e-readers via USB.
Well, these issues appear to be fixed now after two cumulative updates. The system appears to be more stable and therefore I am now confident enough to recommend current Windows 10 users to proceed with the update. So, go ahead and download!
