I appears the discussion on this issue has been closed out but I wanted to pass on my experience regarding this issue.
Hardware: Win 10 Pro on an XPS8900 Dell Computer using the Intel HD Graphics 530 Card.
Problem: Kept getting "IntelCpHDCPSvc Executable Stopped Working" logged as a Critical Event in the Windows Reliability Monitor. Logged times tended to correspond to startup and Windows Updates.
Solution as posted by Intel and suggested by Dell Tech Spt was to roll back driver to 22.214.171.124.63. I kept questioning this solution because Dell for months has continued to show driver 126.96.36.19965 as the recommended (and presumably certified) driver.
Additional information: I started to notice “XPS 8900 ERROR - (A7) Me FW Downgrade - Request MeSpiLock Failed” messages being very briefly displayed during boot up (power on). See Dell Community solution: XPS 8900 ERROR - (A7) Me FW Downgrade - Request MeSpiLock Failed - General Hardware - Desktop - Dell Community
Findings: After Dell assisted me with a sequence to clear up potential BIOS Boot Mode issues, it appears this also solved the Intel Graphics driver problems when using 188.8.131.5265. It's been 16 days since making adjustments to the BIOS Boot Mode and there have been no "IntelCpHDCPSvc Executable Stopped Working" events logged and no need to roll back the driver to the earlier version mentioned in the Intel discussion board.
Hope this helps.
