Also having the same issue with HP prodesk 400, currently have 5 machines stuck on BSOD unable to roll back changes, windows is unable to roll back or even restore back to factory settings.
I manage a call centre with 50 agents all using this machine type and i cant afford for this to take all the machines down!
WHATS GOING ON MS??!
edit: update, looking at reddit and spiceworks people are reporting renaming a drive file HpqKbFiltr.sys to HpqKbFiltr.sys_old - however unable to locate this file on any machine which have the issue (C:\Windows\System32\drivers\HpqKbFiltr.sys)
