Hello,
I have a simple app that uses mdb as a database created in vb6.
For years the app is working perfectly and without a problem on any Windows machines.
Now the customer has bought a powerful machine and the app is lagging on entering simple text into the TextBox, every few seconds for a 2 to 3 seconds while typing the text. The whole app freezes for a second or 2 every few seconds.
No code events are firing on this textbox change or keyup, down,.... events.

The spec for this computer are:
Intel s1700 i9-14900 + 64 GB RAM + 2*960GB + 2TB + 700w
Operating system installed:
MS FQC-10524 ”OEM*Windows11Pro64-Bit

The machine is new (3 months old)
Nothing is running in the background. They use only Office and this vb6 app on it.

I tried with compatibility settings but nothing.
Tried to remove all from the startup, but nothing.
The CPU, I/O, network, no spikes in Task Manager.
Turned off Windows Defender,
Turned off the Windows update,
Tried with unplugged from the local network and from the internet, but nothing.

Very strange, a simple text input on a new strong machine lagging on entering text.

Any Ideas?
