Excessive NVIDIA log or dump nvlog.nvlgstg
Hi All.
I have XPS 15 9570 (Intel + GeForce 1050 Ti MaxQ). A year or so ago I updated it to Windows 11, and a few days ago I looked into the disk usage in Resources. All of the sudden I found an excessive and constant writing by System to some peculiar file `C:\ProgramData\NVIDIA Corporation\nvtopps\nct\nvlog.nvlgstg`. The file grows up to 7 Mb and beyond just in a couple of hours, and if computer is restarted, the file gets overridden and everything starts over again. So, it constantly writes Mb of data to the same file over and over again. Inside the file is a binary data starting with `NvLog dump.` I don't think this is particularly good for the SSD, and there is no reason to constantly write some unknown data to the disk at all. On top of that, the NVIDIA VC is not used at that moment at all. It's idle.
I've checked my desktop PC with a GeForce card, and didn't find anything the like. No constant writing to the file, it stays of the same size. The PC has Windows 10, though.
I've done a clean driver install using DDU, no NVIDIA App installed. No NVIDIA related errors in the Windows log.
Did anybody run into the same issue? What's going on and how to fix this?

FYI The telemetry is the culprit. It writes something to disk literally every 30 sec. But what and why? The GeForce card is not even active at the time.
At the moment, after ~8h of work nvlog.nvlgstg is 17M of size.
Re: the driver on my desktop doesn't have this issue.

For the time being I fell back to the official driver from Dell (528.79), which apparently doesn't have this feature responsible for writings to `nct\nvlog.nvlgstg` at all.
It turns out the official Nvidia drivers for notebooks doesn't work properly with Dell XPS. You can't have the latest one on your machine.
