In recent times after Windows 10 updates to my PC's system, Windows has slowed and audio now has clicks and pops and application take sometime to load. I have looked at many possible solutions here and on the web, but can't find a solution. Windows 10 was working OK in earlier versions. I think I have tied it down to the network and Latency Monitor sort of indicates this (see Below). I have the most recent drivers, but I think the drivers loaded are the ones causing the issue. The HP PC is 10 years old and many drivers for the HP PC are not supplied by HP for Win 10 only Vista. I have tried the Vista drivers to no avail even though they use to work in earlier version of Win 10.
After Windows has started things run OK for a time but gradually gets worse.
All seems OK in Safe Mode.
Any suggestions

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:00:38 (h:mm:ss) on all processors.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
