RIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: ffffa707c7191504, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff801bb9832d2, address which referenced memory

Is there a need to look at the DMP file? I know that all files related to kbdclass.sys are created in the same way.

Rich (BB code):
*** WARNING: Unable to verify timestamp for HKKbdFltr.sys

In the registry, you need to remove the HKKbdFltr driver in Kbdclass and mouclass values.

I asked for the full specs because these fora are for the support of PCS builds only and so we need to be confident that this PC is a PCS build.

Telling the OP to remove a filter driver without warning them of the potential issues and risks in doing so is a tad unwise don't you think? You do appreciate that the warning message you quoted only indicates that symbol files for the specified driver were not installed in the debugger? It doesn't indicate that the driver was necessarily the problem. If/when the user posts the full spec I may ask for the dump file to be uploaded so that I can fully analyse the dump and provide a considered and evidence based response.
