I experienced this issue yesterday when attempting to upgrade to the Windows 10 Anniversary Update. About 70% through, a Blue Screen appeared with the error code IRQL_NOT_LESS_OR_EQUAL. I have used Bluescreenview to find the address that caused the problem, which appears to be ntoskrnl.exe+149f90, and caused by the driver ntoskrnl.exe. I have attempted to use the tool provided by the forums for blue screens, however as it was during an update the minidump copying failed as the minidump is located in C:\$WINDOWS.~BT\Sources\Rollback\setupmem.dmp. I have uploaded the minidump to setupmem.dmp - Google Drive.
After the bluescreen occured, a screen appeared that read it was reverting changes, and windows booted normally afterwards, however without updating.
Thanks, and I appreciate any help.
