Windows – How to uninstall all Citrix driver from Windows Server 2008 R2 Guest if BSOD on safe mode

Some simple troubleshooting methods here:

1. In Safe Mode (that's a good sign that you can boot into Safe Mode, BTW), go into the MSCONFIG utility and use the process of elimination with the Services, Startup and General tabs to hopefully isolate the potential causes of the problem. That will give you a great base of operations to fan out from in the troubleshooting process.
2. Hopefully you can then boot into normal mode and uninstall the Windows updates that you previously installed. BTW, uninstalling doesn't work in safe mode since the Windows installer service doesn't start except in normal mode.
   3. Having said that, can hack Windows machines to uninstall even in safe mode using this method. Your mileage may vary.
3. You could go semi-scorched earth and repair the boot files using the installation disc: http://social.technet.microsoft.com/Forums/en/winserversetup/thread/cd3d665f-3d95-4617-946d-55d8c03448fe

This looks like the issue described in the following KB article:

https://support.microsoft.com/en-us/kb/2359223

"0x0000003B" Stop error occurs in Windows Server 2008 R2 and in Windows 7 when an application or a service performs a GUI-related operation

The reason I think it is the issue described in the hotfix is because it specifically calls out the win32k.sys driver. Also, the CSRSS.exe process which also shows up in the dump is used in inter-process communication between user-mode GUI operations and the kernel which is also indicative of the issue described in the hotfix (reference: https://en.wikipedia.org/wiki/Client/Server_Runtime_Subsystem).

I would recommend applying the hotfix in the KB article and monitoring to see if the stop errors continue.
