I've been dealing with mysterious high CPU utilization from WmiPrvSE.exe for MONTHS. I finally did some digging using (run wmimon from an elevated cmd prompt). Guess what the culprit was?github.com/luctalpe/WMIMo… Freaking Dell Alienware Command Center! I don't even remember installing it; it may have been automatically pushed via Windows Update. 😡 Image

OK, so there is definitely a problem with the Search-UnifiedAuditLog cmdlet in #Microsoft365. Confirmed this in multiple tenants - here's what I'm seeing: 🧵

#threathunting #threathunt #auditlogs #M365 #Office365 #O365 #M365Security First, go to security.microsoft.com -> Audit and perform a new search for all events in a given timeframe (a few hours, total). Have this available for reference.

I think a 40" 5K2K monitor is about as perfect as you can get for a regular desk setup.

I know this pushes graphics performance/bandwidth to the limit, and these displays don't go north of 60 Hz - I'm putting those things aside. If you were to take a 40" 5K2K monitor and superimpose a 4K monitor over it of the exact same height, the 4K monitor would be 32" diagonal.
