Anybody else having driver difficulties with Build 14926?

Installed the latest preview on my Dell Venue Pro 7139 last night, then spent a couple of hours cleaning up driver issues. It ate my Dell/Atheros 1537 WiFi/BlueTooth drivers completely, and rolled back Intel HD Graphics, Intel MEI, SMBus controller, memory controller, and more. I'm curious to know if it's just this machine, or if others have experienced similar difficulties.
This used to happen back before the Insider Preview program got started, before Windows 10 was officially released on 7/29/2015. But it's been a while since I've seen these kinds of gyrations.
Thanks,

The only problem I have is itunes not detecting my phone. This happened awhile back and was corrected with a clean install. I Just don't feel like clean installing right now. ASUS G750

P.S. I had to reinstall the apple usb driver.

P.P.S. I clean-installed Thursday and all worked the first time!

I've been having issues with slow loading between webpages off and on so far since installing build 14926.

I had issues with the Intel G33 drivers - I had to go to the Microsoft Basic Display Adapter.

Refreshing the DNS address on the router finally sorted it.

Wow, Brink! That's really interesting. You'd think the DNS cache would either work or fail. Strange that it simply slowed things down. Maybe it was some non-optimal routes or something? Bizarre.

Still can't view my NAS or my 2 My Book Live drives?
This was NOT fixed from the last build. Why is it that MS can ruin it then fix it then ruin it AGAIN?

I can only guess that it was something on the ISP's end that this toggled it to work properly again. It was odd.

No driver problems on my desktop.

I've had issues with Build 14915 and 14926 on a Dell Inspiron 530S Desktop with the Intel G33 display adapter and no SSE4.1 listed in the BIOS, had to back to 14901 which works well, haven't found 14905 again which worked really well.
