Since upgrading from windows 7 to 10 my pc has been slowed down to a crawl by periods of very high cpu usage. A major culprit, but not the only one, is local security authority process.
This makes the laptop overheat , reduces battery life and slows work to a crawl.
I have run sfcscannow and dism as administrator and no fault has been found..
Help please

Best to do a clean install in-place upgrade Windows 10 - Clean Install
When prompted, choose to keep all settings and apps.
Have you made sure all your drivers are up to date?
i had this problem but my system performance had become very bad.. i just typed verifier in run and than deleted existing settings and restarted...That solved my windows slow down and high cpu usage problem.
Nothing to indicate driver problem--no update required according to slim drivers and no exclamation marks against any driver in device manager.
Verifier sounds a little worrying for a intermediate pc user - any less dangerous routine..
Problem lasts for 5 to 10 minutes and then goes away which suggests it is not a driver problem.
Have run Kaspersky antivirus scan, malwarebytes scan, Spybot, and ADW(?) scan with no fault foun
