I vented here previously about issues caused by the upgrade from Win7 Pro to Win10 Pro on my desktop. The problems I encountered were relatively easy to fix, once I understood them, but I was cursing a blue streak for a day or so till I discovered and applied the fixes.
Now I have yet another. I dual-boot Windows and Ubuntu Linux on the desktop machine. I awoke yesterday to see the desktop at the Ubuntu login screen. This means a reboot occurred, as Ubuntu is the default choice the machine boots into if I don't intervene. Ask expected, Windows Updates got delivered and applied, and required a reboot.
Fine. Reboot into Windows.
Something in the latest updates gave the machine heartburn, as I had a new and different BSOD, this one announcing REGISTRY_ERROR as the problem. I had two more before I gave up and rebooted into Linux, and two of them occurred when I wasn't actually
using the machine. If I boot into Win10 and leave it at the Windows desktop, it
will BSOD with a registry error.
Now I get to try to figure out what causes the problem, and remove the Update that triggers it.
I think I also vented about having problems connecting to my Android tablet after upgrading to Win10.
When I plug in the tablet via USB cable, what
should happen is that Android sees it's plugged in, and presents a screen where I can turn on USB Storage. Do that, and the internal SD card in device flash and the external microSD card in a slot get dismounted by Android and attached by Windows. Icons representing them appear on my Windows desktop, and I can use Windows Explorer to open them as drive and explore the contents and do file transfers. (The usual reason I do it is adding eBooks to the microSD card from Calibre.) When I finished, I turn off USB Storage in Android, it remounts the drives, and they disappear from Windows.
After upgrading to Win10, that started to fail. I could connect the tablet via USB and turn on USB Storage. The drives would appear in Windows, and I could do file operations. But when I turned
off USB Storage, things went to hell in a handbasket. The drive icons did not disappear from the Windows desktop, and Windows would get into a state where I'd have to reboot to return to sanity.
It appears the problem was actually on the tablet end.
Android has a Developer Options setting where you can turn on USB Debugging, intended for developers who want to connect to the tablet and do remote debugging from a host. On my older tablet running Android 4.2 Jellybean, USB Debugging was off, and had to be enabled to root the tablet. But I had to turn it back off again once I had, because having USB Debugging on interfered with using USB Storage. On the newer tablet running Android 4.4 KitKAt, USB Debugging was on by default, and if I plugged it in via cable I got a choice of enabling USB Debugging or USB Storage.
I'd already rooted the device, so I decided to turn off USB Debugging.
That seems to have been the cause of the behaviour I was seeing. Since USB Debugging didn't interfere with USB Storage, I turned it back on. On impulse, I tried connecting via USB cable. Everything worked as it should. I could mount the drives from Windows, and transfer eBooks with Calibre. When I was done, I could turn off USB Storage and Android would remount the drives and they would disappear from Windows, and Windows would not go to Neverland.
Yes, I'm glad to have found a fix, but no, I have
no idea what was going on.
