PC slows to a halt, disk transfers stop, internet stops

I’ve made sure blackbird.exe is on the desktop, and rebooted.

so you ran this in elevated command?
%userprofile%\Desktop\blackbird.exe -i -l

[Malnutrition]

Right Click Autoruns and run as admin, uncheck the items i highlighted and reboot.





Type One Drive in the search and uncheck all.
Same with Edge

[sisom]

so you ran this in elevated command?

Yes, as administrator.
I’ll do the Autoruns stuff now and reboot, thanks!

So that should have fixed the error below, can you confirm?
Settings: SystemSettings.exe
The system detected an overun of a stack-based buffer in this application.
This overrun could potentially allow a malicious user to gain control of this application.

Hi, yes, it’s fixed that error. I have rebooted, and am running FreeFileSync again on my 8TB drives, M and N - this time, no slow downs, it has checked almost 6 million files in 12 and a half minutes, much faster than before. Now I will run the copying part and see if that slows down, thank you so much for your continued help!

Ok, I think that a windows update slipped in and changed a couple settings we made.

So do this:
Open elevated command:
Copy this and paste:
powershell -Command “irm https://christitus.com/win | iex”

Hit enter.

Go to updates tab click security settings.

Go to Tweaks make sure these are ticked.

Then click Run Tweaks, allow it to complete then close it.

Then re-download and run the batch file i created for you, as administrator.

[COLOR=rgb(243, 121, 52)]Make Certain to Reboot the machine after the batch file runs.

This will recreate the error.
Settings: SystemSettings.exe
The system detected an overun of a stack-based buffer in this application.
This overrun could potentially allow a malicious user to gain control of this application.

So you will want to run:
%userprofile%\Desktop\blackbird.exe -i -l

Again and reboot.

This will prevent windows from reverting any changes we made, it will now only install security patches.[/COLOR]

The copying part of FreeFileSync is performing the same as before - slowing down to 0 bytes/sec and then back up to around maybe 5MB/s max, but sticking at 0 bytes/sec for at least ten seconds, and this is while copying a file that is several GB in size, so not loads of little files (at this point in time).

OK, see my last post. 21

Thank you very much, I am running the Tweaks part now, it is on Disk Clean up at the moment, I will follow the rest of your instructions and get back to you, many thanks!

Hi, I’ve run
%userprofile%\Desktop\blackbird.exe -i -l
and rebooted, and I can now view the Network Settings without the error message coming up,

[Malnutrition]

Run again and reboot. This time only -i

[sisom]

Okay, I will run it again with just -i.
I have just started trying SyncBackFree, as an alternative to FreeFileSync - in Task Manager, I am seeing a huge difference - Average Response Time on the hard drives (spinning discs, 8TB) is 3-4 ms - when using FreeFileSync, I was constantly seeing 1,000 ms to 4,000 ms or longer Average Response Time.
I’m just running a simulation with SyncBackFree, I’ll reboot as soon as it’s done and post back here, thank you so much for your help.

[sisom]

I’ve run it and rebooted.

[Malnutrition]

About the error?

[sisom]

The error message still doesn’t display when I view Network Settings.
