I didn't check those updates, but usually the spike is caused by .NET updates and the .NET Framework recompiling changed assemblies.

Hi,

What you can try is..

Uninstall Each Security Update/Patch and check CPU Performance and if a server comes back to normal CPU uSAGE after uninstalling a particular patch then it is the culprit.

Hope that helps :)

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

You can use
a) Performance Monitor, and let it record data in real-time; e.g. CPU and memory load per specific process. The data will get collected for later analysis with Performance Monitor. Collection can even be triggered by e.g. 50% sustained CPU load over 5 minutes.

b) ProcMon from www.sysinternals.com to monitor ad-hoc, provided you get access to the machine while it has high CPU or whatever load

There are options, as you can see, but usually you have to drill down to the issue, narrowing the focus from very general (i.e. system load) to very specific (i.e. process load).
