Windows 10 blue screen of death
Actually HP computers are not the only product affected for this issue other computers as well like DELL etc. That’s why for now, we’ve temporarily paused the update for people who seek to check for updates, to investigate an isolated reported issue and will make it available for download again once ready.
To solve this problem, go to Troubleshoot -> Advanced options -> Command Prompt and enter the following command:

cd c:\windows\system32\drivers

ren HpqKbFiltr.sys HpqKbFiltr.sys_old

After restarting the device, the Windows 10 system can be successfully loaded. According to the Microsoft support community, Microsoft has acknowledged this blue screen issue and suspended the release of this cumulative update.
