Windows 10, 1709 experincing Credential Guard and Key Guard consistently and continuously running at 35% - 45% CPU, causing the entire computer to slow down. Tried upgrading to 1803, disabling Symantec Antivirus and making sure all bios and drivers are updated with no luck.
This is an enterprise system with bitlocker secure boot required so we cannot disable Credential Guard.

Hi cruzenbye,
Please check the Windows Defender Credential Guard: Known issues involving third-party applications (high CPU usage):
/en-us/windows/security/identity-protection/credential-guard/credential-guard-known-issues
Take the following steps to collect performance monitor log when the CPU is high.
a. Open an administrator command line and run:
Logman.exe create counter Perfsystem-5sec -f bin -max 500 -c “\LogicalDisk(*)\” “\Memory\” “\Network Interface(*)\” “\Paging File(*)\” “\PhysicalDisk(*)\” “\Server\” “\System\” “\Process(*)\” “\Processor(*)\” “\Cache\” “\NTDS\” “\DirectoryServices(*)\” “\netlogon(*)\” “\Database Instances(*)\” “\Security System-Wide Statistics\” “\DNS\” -si 00:00:05 -o C:\PerfMonLogs\Perfsystem-5sec.blg
b. Run “logman start Perfsystem” to start collect.
c. Run “logman stop Perfsystem” to stop performance monitor tool. Run “Logman delete perfsystem” to delete the monitor template.
d. The log is located in C:\PerfMonLogs\ Perfsystem-5sec.blg, upload it to your OneDrive and post here.
Here is a thread for your reference:
Thanks for your cooperation.
