My fellow Internet Press Guild member and long-time Linux and Windows watcher Steven J. Vaughan-Nichols waxes both eloquent and aggravated in this ComputerWorld article on the recently-released script fix from Microsoft. Here's a snippet:
Microsoft may need a refresher course on what constitutes good software support.

Almost a week after some Windows 10 PCs got trapped in reboot hell, Microsoft finally issued a patch — make that “a kludge of a script” — to finally enable affected Windows 10 users to get their machines working again.

The fix, “Windows 10 1607 Script fix to unblock update for Windows Insiders,” doesn’t explain what’s going on. It does work, however.
