Marcos, I have sent you a private message with the information you requested. The physical memory of the computer is 80GB.

I have the memory dump file, but it is enormous in size, and I don't think this is normal. The file is approximately 84GB; when I compressed it, it became around 3GB. Could you please advise me on how to send it?

Yes, there wasn't an update with this KB number.

C:\Windows\System32>systeminfo Host Name: ComputerName OS Name: Microsoft Windows 11 Pro OS Version: 10.0.22621 N/A Build 22621 OS Manufacturer: Microsoft Corporation OS Configuration: Member Workstation OS Build Type: Multiprocessor Free Yes, it is Windows 11 Pro 22H2. I couldn't find a reason why it can't receive this update either. @Marcos with the link you mentioned in your previous message, I managed to complete the request, and I received a delivery confirmation email. I haven't received a support ticket ID yet, but I believe they have received it and will be able to open it shortly.

I would also like to mention that I am unable to contact support as my emails are being bounced back with the message "550-5.7.26 Unauthenticated email from mydomain.com is not accepted due to 550-5.7.26 domain's DMARC policy." Due to this issue, I had to send the email from Outlook instead of using the website's contact form. However, I have not received any response or even a delivery confirmation yet.

Unfortunately, the Windows Update cannot be installed on our computer, as evident from the image below. I followed your instructions and uninstalled the ESET Endpoint from the computer. The MD was successfully registered in the Microsoft Security Center. During that time, the copy-paste function was working normally. However, when I reinstalled the ESET Endpoint, the issue reappeared. Disabling the Media to scan (Local drives & Network drives) allows the file copying to function properly. I believe I have encountered an impasse, and the only option at this point is to await the release of a Windows or ESET Endpoint update.

Due to my own mistake, instead of searching for Microsoft Defender in the Group Policy Editor, I was searching for Windows Defender. Upon taking a second look, I found it, and indeed, it was set as "Not configured." I changed it to "Enabled" to see if it would make a difference, but unfortunately, nothing changed. Will I need to restart first for it to take effect? Additionally, I wanted to mention that after the previous attempt with the script, I re-enabled MD using the second script available on GitHub, which activates MD again.

Thank you very much, everyone, for your efforts to assist me. I greatly appreciate it. Before reaching out to you here for my issue, I did quite a bit of research on the internet. I came across a relevant article and other similar ones that highlighted the problem, particularly related to disk issues (especially when transferring files from a mobile phone to a computer). For this reason, I ran a disk check on both local drives of my computer and also performed an sfc /scannow in case there was an issue with any operating system files. Both checks did not find any problems. Therefore, I focused on the antivirus and discovered that the issue stops when I disable the real-time scanning of ESET. @Marcos, I'm not sure if what you asked me to do will be useful since MD is currently inactive. However, if you believe it will help us draw a conclusion, I will gladly do it. Unfortunately (or fortunately), I won't be at the office over the weekend, so I will be able to check again from Monday onwards. If I manage to work remotely during the weekend, I will provide an update. Once again, thank you very much for your time and your efforts to assist me.

I have not received an automated response from the system with the ticket ID. Additionally, I was unable to upload a file larger than 20MB. I submitted the request through the website as well as through Outlook to the address esetgr.com.

This is the usual method I use to copy a file, but just to anticipate, I have also tried using the mouse and Ctrl+C Ctrl+V.

I am copying using Windows Explorer, but I also tried Terracopy without success.

Unfortunately, after disabling MD using the script and restarting the computer, the issue still persists. I have not received any response from the support team yet. I hope to receive a response soon.

The issue persists even when copying files between local drives. I plan to try the suggested solutions within the day, and I am confident that we will achieve a favorable outcome.

Thank you @itman I will try to disable the Tamper Protection prior to disabling the MD and I let you know the results. I have already raised a support ticket so I am waiting for their reply too. As I have explained earlier, I do not have the "Microsoft Defender Antivirus" option in the Group Policy Editor, so I guess I have to disable it through Regedit. In any case, I will post here the outcome of all of my actions soon.

Our machine is connected to a domain maybe this is why it does not have this option. Thank you for being so helpful Marcos you are so valuable.
