The WinCC is running on VMware Workstation 16 Pro. Normally, the faceplate takes 500ms to open, but on this server, it sometimes takes up to 4 seconds to open the faceplate. I have checked the WinCC diagnostics and found nothing. I also checked the Windows event log and found it is filled with the following: Kernel General Event ID 1 Information,18/03/2025 3:44:45 PM,Microsoft-Windows-Kernel-General,1,(5), The system time has changed to ‎2025‎-‎03‎-‎18T07:44:45.051935200Z from ‎2025‎-‎03‎-‎18T07:47:42.995468800Z. Change Reason: An application or system component changed the time. Process: '\Device\HarddiskVolume4\Windows\System32\svchost.exe' (PID 3540). Information,18/03/2025 3:46:11 PM,Microsoft-Windows-Kernel-General,1,(5), The system time has changed to ‎2025‎-‎03‎-‎18T07:46:11.631000000Z from ‎2025‎-‎03‎-‎18T07:43:13.691270700Z. Change Reason: An application or system component changed the time. Process: '\Device\HarddiskVolume4\Program Files\VMware\VMware Tools\vmtoolsd.exe' (PID 3632). Information,18/03/2025 3:41:30 PM,Microsoft-Windows-Kernel-General,1,(5), The system time has changed to ‎2025‎-‎03‎-‎18T07:41:30.305180400Z from ‎2025‎-‎03‎-‎18T07:44:28.244839400Z. Change Reason: An application or system component changed the time. Process: '\Device\HarddiskVolume4\Windows\System32\svchost.exe' (PID 3540). The change in time backward and forward is nearly 3 minutes. Could this be the reason for the slowness of WinCC? Please if anyone has experienced the same issue ? Best regards, Tech Ahmed

However, some points to check would be: Check that the VM resources are sufficient. That there is sufficient storage. Make sure you have the latest update compatible with your WinCC version. Review the network settings in the FAQ: What are the requirements for operating SIMATIC WinCC in a Windows network? - ID: 868014 - Industry Support Siemens BR BRCookie_M0nster

WinCC is V7.5 + SP2 + Upd6 and "lets Windows choose what's best for my computer" is selected for performance. I have also attached the WinCC Log.

Is it a LTSC Verison in your case? its because only the LTSC Version of WinServer 2019 1809 is released with WinCC V7.5 SP2 I´m not sure if this should be the reason but we have to be careful always with software compatibility: https://support.industry.siemens.com/cs/de/en/view/64847781 Bye Murof
