Hello,
My laptop is experiencing minor lags and stutters
I'm providing the Latency monitor reports and it seems that "storport.sys" is causing a problem.
Please help me fix this issue

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. 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 0:01:28 (h:mm:ss) on all processors.

Computer name: DESKTOP-HDCSFDC
OS version: Windows 10, 10.0, version 1909, build: 18363 (x64)
Hardware: X550JX, ASUSTeK COMPUTER INC.
CPU: GenuineIntel Intel(R) Core(TM) i7-4720HQ CPU @ 2.60GHz
Logical processors: 8
Processor groups: 1
RAM: 8081 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2594 MHz
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

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): 419.20
Average measured interrupt to process latency (µs): 3.302428
Highest measured interrupt to DPC latency (µs): 415.60
Average measured interrupt to DPC latency (µs): 0.907226

REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation
Highest reported total ISR routine time (%): 0.000165
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Total time spent in ISRs (%) 0.000229
ISR count (execution time <250 µs): 848

REPORTED DPCs
_________________________________________________________________________________________________________
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: searchindexer.exe
Total number of hard pagefaults 775
Hard pagefault count of hardest hit process: 285
Number of processes hit: 46
