In response to this bug:
”Cursor seems to be spawning a telemetry process whenever the IDE is opened. If I just open any Javascript file this process will start spawning/killing powershell processes indefinitely which is eating all my CPU.”
I just created a full fix for this!
I did track it down to the telemetry of the built-in “typescript and javascript language features” extension. I cloned the vs-code source and found the extension. Ironically, I was able to use Cursor to find the bug (although thanks to Claude 4.5). I then created a simple workaround by not initializing telemetry for that extension.
I’ve submitted a PR back to vs-code; kind of doubt they’ll merge it in.
In the meantime, I created a public repo with a script that will patch your Cursor installation.
There was also mention that you could disable all telemetry in vs-code and that would fix it, but I was unable to find that setting (is it somehow missing in Cursor?)
Here’s the fix:
