Windows 10: Weird Activities On System Security Logs In Event Viewer

Recently, I checked my system security logs in event viewer and found some weird Audit Success Log on and some other activities on my computer at the time when i was sleeping. Is that mean someone remote logged on my pc and steal my information? Some of them has the security ID is the name of my device and user, some has security ID is SYSTEM and some has weird ID and name like the image below. Someone please help and tell me what to do!

thousands of security logs in event viewer

it's weird, the CMD command doesn't show the security log number, it only shows the word "Security" but it's blank. The power shell however does show. And since I wrote the post, I got 1000+ more, and Event Viewer even added Exclamation mark next to the number. It shows: 13110(!) New events available

EventID are mostly 5379 and 4798.

Powershell output:

Oh so I guess it's something normal?

Hello @mibaup,

Run the command below in a CMD Prompt to list the total entries for EACH log . . .
Code:

Example output . . .
Code:

You could then run it AGAIN after about 5 minutes to see if there is a VAST difference in the totals. This should hopefully highlight any unusually drastic operations taking place, if ANY.

Just a thought.

The command in PowerShell [ if you prefer ] is . . .

I hope this helps.
