Windows 10 Upgrade BSOD (SYSTEM_SCAN_AT_RAISED_IRQL_CAUGHT_IMPROPER_DRIVER_UNLOAD)
After the Windows 10 setup files have downloaded and its rebooted into the upgrade process we seem to be getting this weird problem.
After the files have copied across (so the first part of the upgrade process) when its doing the installation/configuration i get a BSOD with the following error :
SYSTEM_SCAN_AT_RAISED_IRQL_CAUGHT_IMPROPER_DRIVER_UNLOAD and i cannot seem to figure out what the cause is.
Machine Specs:
- OS: Windows 8.1 Pro
- CPU: Intel Core i7 4790K Haswell Refresh Processor 4.0 GHz
- RAM: 16GB PC3-10666 1333MHz DDR3 Memory (2 x 8GB sticks)
- GPU: NVIDIA GeForce GT740
- MOBO: Asus B85M-G Basic Micro ATX Motherboard
- Hard Drive Setup: All our machines have 1 SSD boot drive and 2x1TB Mechanical drives in a raid 1 setup
We have 2 other machines built pretty much the same and both of them have upgraded no problem, any ideas?

Your crash SYSTEM_SCAN_AT_RAISED_IRQL_CAUGHT_IMPROPER_DRIVER_UNLOAD (d4)is caused by the driver spac.sys which was unexpected unloaded.

SYSTEM_SCAN_AT_RAISED_IRQL_CAUGHT_IMPROPER_DRIVER_UNLOAD (d4)
A driver unloaded without cancelling lookaside lists, DPCs, worker threads, etc.
The broken driver's name is displayed on the screen.
When possible, the guilty driver's name (Unicode string) is printed on
the bugcheck screen and saved in KiBugCheckDriver.
An attempt was made to access the driver at raised IRQL after it unloaded.
If kernel debugger is available get stack backtrace.
