_________________________________________________________________________________________________________
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 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 0:01:32 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 13847.60
Average measured interrupt to process latency (µs): 48.963643
Highest measured interrupt to DPC latency (µs): 13807.30
Average measured interrupt to DPC latency (µs): 46.532225

_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

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.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: spotify.exe
Total number of hard pagefaults 355
Hard pagefault count of hardest hit process: 217
Number of processes hit: 11

// What I tried :
Reinstalling my focusrite drivers
Changing USB port (Tried USB 2.0, 3.0 and 3.1)
sfc scannow
updating all my drivers, including audio drivers in device manager
Going back to a previous driver of my focusrite
updating windows
restarting audiodg.exe when it's popping
resetting all my focusrite settings
run the audio troubleshooter
Uncheck the box to "Allow Application to take exclusive controls on this device"
// S.O.S.
I'm open to all suggestions. But I can't uninstall the last update of Windows, and I don't know why
