Hi Chethan,
Thanks for your message. Unfortunately I just found a workaround for this annoying issue which started for me after February 8th 2024. What I can tell you is that if another application is looking for a pogram (.exe) or dynamic library (.dll) in the directory it cannot execute it. The effects of this I do not know. I am sorry for that. Also your question about the purpose of the HP Telemetry directory (and folder) I cannot answer.
I have had some contact with HP Support and there might be a change that my research and workaround will make it to the software developers by which we might get some answers. Sorry that this is all I can answer to you.
I am still without unexpectely changes to 'racing mode' on my Philips 34" monitor model 346E2C.
