Does the below file exist in your profile?

"extension_garbage_collector.cc" is a Chromium source file:

https://chromium.googlesource.com/chromium/src/+/8496f370f/chrome/browser/extensions/extension_garbage_collector.cc

... and

https://learn.microsoft.com/en-us/answers/questions/3890397/what-is-this-in-the-event-viewer

I personally wouldn't worry that much about this; it's just an "informational" event, pertaining to "normal" browser functionality associated with its extensions system ...

So why doesn't the log entry appear with the 64-bit version of Supermium on Windows 10?
It only appears on the 32-bit version on XP.
Both have identical extension setups.

I would have to assume (but it is strictly an assumption) that it is due to the INFERIOR memory management of 32-bit OSs and the "cheap workarounds" that 32-bit software have to employ.

Even on 64-bit OSs, there is a very VERY drastic difference in memory management in 2016 OSs versus 2021 OSs.

I cite specifically the FIRST RUN after a reboot or hibernate of all Chrome variations.

EXTREME lags on that FIRST RUN on certain hardware in 2016 OSs but NO LAG on 2021 OSs on the same exact hardware.

I've done some more tests, and FWIW, the log entry only seems to be written when Google Sync is enabled.
If I log out of Google Sync, it doesn't happen.
My guess is that it's something to do with the extensions sync process.
That still doesn't explain why it doesn't happen on the 64-bit Windows 10 installation of course!

The Registry entry should NOT be there, I agree.

I once tested a program on the Desktop, and it automatically added its own entry (program name) in one of these Registry locations, and it showed a similar Event Viewer message, that's why I mentioned it.

Any command line put in those registry locations will be run when the system starts, so I always check those locations every time I install anything new, just to see what it might be running behind my back!

Check if you have a "Supermium" entry in your Registry in these locations:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]

IF you have, deleting it might fix your event viewer problem.

same as daveh said, no such thing in any of those. and some of those directories dont even exist, the "policies\explorer\" and the runonce ones dont exist, so no. - and yes i know vistalover said it's just "information" and i get that, but i just find it annoying that i see hundreds of these nonstop in only a period of a few months. and i saw those exact reddit threads before you posted them, but no solution on how to get rid of the stupid message.

and woa hey that actually worked - what daveh said about the "sync" thing - did a search for "sync" in the settings screen, then saw this like "disable to sign in to sites without serpimum" or something, turned that off... then close and reopen browser a bunch of times, and it's no longer making that message appear anymore. so it worked. thank you so much dave-h

edit: wait a minute... no it did "not" fix it.. it still keeps appearing. so that was not the solution.. so something is still wrong. it seems to still appear somehow even while the browser is open (instead of closing/opening it) - it seems to appear again about 30 seconds after letting it sit there idle after opening. this is really annoying.

chrome://flags/#enable-webassembly-garbage-collection   WebAssembly Garbage Collection
I don't know what the "Default" is, but try setting it to "Disabled".

That flag doesn't seem to exist in my Supermium installation.

Are you sure you've disabled Google Sync completely?
Do you have an avatar icon to the left of the three dots top right of the browser window?
If so, click on it and make sure it says that sync is off.

Not here either.  But I also may be a version or two behind.

like the other guys said too, that option dont exist when i checked. and yea i double-checked everything again - to daveH. i've never clicked that little person avatar icon ever before but.. no it doesnt say anything about sync... and here just to show the stuff is turned off...but "still" logging the stupid thing.

Yes, the flag is present in the version that I use, v122 :
WebAssembly Garbage Collection
Enables the experimental Garbage Collection (GC) extensions to WebAssembly. – Mac, Windows, Linux, ChromeOS, Android, Fuchsia, Lacros
#enable-webassembly-garbage-collection

But it is NOT present in v144 .

Since the flag is not present in v144, this probably won't work, but it's worth a try maybe:
add switch  --disable-webassembly-garbage-collection  or something similar.

i had to reintall windows i cant find where supermimr installls wher it it please

It installs in C:\Program Files\Supermium unless you tell the installer otherwise.

nope no difference still always appears 30-ish seconds after opening - but... fine i'll give up then... it's impossible to ever stop this stupid crap from flooding the event log thing forever.
