[SOLVED] - DPC latency from classpnp.sys

I could hear light crackling noise from my PC so i decided to run dpc latency checker and the graph showed everything to be yellow and it said there's nothing wrong with my system, then I installed latencymon and it said classpnp.sys is causing the issue. Can any windows 10 masters help me fix...

Internet, yes?

With that old OS that haven't got any security updates for years, that's like an open door for all kind of worms and malware attacks.

What firewall/antivirus do you use on those OS'es ?

Windows 10: Avast
Windows 7: Malwarebytes, I even updated it fully using Legacy Update (I had a fully updated machine in 2023 but I formatted it since it had useless apps)
Windows XP: Comodo Firewall

I use my common sense to protect myself from viruses and never click on shady links. I mainly use this to watch yt/browse stuff like a 2nd screen pretty much.

And for XP i have the edition for AMD64 compatible processors (the one from 2005, Pro X64 edition) and that version is fully utilised using Legacy Update aswell, except Tiny10 which i installed for fun (I use it once every week day)

Ok so you have at least some protection in place. What about backup (personal files) in case it still get to pick up some nasty ransomware ?

Oh I do not have any personal files, I keep them all seperately on my laptop (so pretty much my backup files are on a seperate device, these OSes are just there to be used sometimes to browse pretty much).

I do not think I got any viruses, I did scan using AVG and Malwarebytes, and no viruses, so pretty much I do not seem affected!
