I rebooted my computer to this lovely Blue Screen Of Death (BSOD) message:
bcdedit /store C:\boot\bcd /debug on
bcdedit /store C:\boot\bcd /dbgsettings net hostip:192.168.1.101 port:49152
I needed to set the “/store” parameter to ensure I was manipulating my non-booting BCD file, and not the BCD file that Windows Recovery boots from. Write down the key or save it someplace, you’ll need it on the ‘host’ computer (see in the above screenshot).
It turns out you need to enable symbols or else you get an incomplete picture. After enabling symbols and running !analyze -v I got the following:
ctxusbm. This is a Citrix driver for their Receiver client that passes through USB to a Citrix session. I had updated Receiver to 126.96.36.19914 last month and I probably hadn’t rebooted my computer until Windows Update made me. So that’s probably why I’m experiencing this issue now. To fix this issue, I rebooted into the Windows Recovery mode and deleted all instances of ‘ctxusbm’ from the SYSTEM hive. Specifically, I deleted these locations:
Upon the next reboot, my computer came back cleanly and operates without any issues. I am going to keep this module removed until the next version of Receiver is released, hopefully, I won’t have any more issues. Issues with ctxusbm seem relatively prevalent with Citrix.
