Windows 10: "One or more DCP routines that belong to a driver running in your system appear to be...

So I've been having some stuttering issues in games and big performance drops then it'll go back to normal. I've also noticed that my friend with the exact same computer Dell G7, same specs doesn't get these and his runs smoother. I ran the whysoslow monitoring tool from Resplendence, and that told me to run LatencyMon. Here is the result I bolded the important parts:

CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 0:11:49 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: 1960.30
Average measured interrupt to process latency µs: 5.290084

Highest measured interrupt to DPC latency µs: 1921.90
Average measured interrupt to DPC latency µs: 1.948345


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

Highest ISR routine execution time µs: 236.650362
Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total ISR routine time %: 0.004625
Driver with highest ISR total time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Total time spent in ISRs % 0.007684

ISR count execution time 2000-3999 µs: 0
ISR count execution time >=4000 µs: 0


_________________________________________________________________________________________________________
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.

Highest DPC routine execution time µs: 1947.862319
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

DPC count execution time >=4000 µs: 0


_________________________________________________________________________________________________________
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: chrome.exe

Total number of hard pagefaults 595
Hard pagefault count of hardest hit process: 178
Number of processes hit: 24

DCP Latency due to ACPI.sys drivers

Hi

Using my laptop (lenovo legion y530) with audio is almost useless, due to clicks and sound disrupts in the recorded audio.

LatencyMon says

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 0:00:41 (h:mm:ss) on all processors.

The most troublesome drivers are

Highest ISR routine execution time (µs): 110,984601

Driver with highest ISR routine execution time: ACPI.sys - ACPI-drivrutin för NT, Microsoft Corporation

Highest reported total ISR routine time (%): 0,001352

Driver with highest ISR total time: ACPI.sys - ACPI-drivrutin för NT, Microsoft Corporation

Total time spent in ISRs (%) 0,001631

I have tried all the optimization tricks I have found, and then some, but the problem persists. I have seen a number of others with the same problems. Is this something Microsoft are working on, or do we simply have to switch to Apple?

All the best

Windows 10 Home Microphone Issues

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. Also one or more ISR 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.

 

Taskbar bug: switching to another window -will not appear at the front


Follow either of these steps to fix the issue with the Active window hiding behind.

Method 1:
I suggest you to disable window by hovering over it with the mouse and check if it helps. To do so I suggest you to try the below given steps and check if it helps:

1. Press Windows key + X key and click on Control Panel.
2. Select or click Ease of Access.
3. Click or tap onEase of Access Centre.
4. Click on Make the Mouse Easier to Use was uncheck Activate Window by hovering over it with the mouse.
5. Check if issue is resolved.

Method 2:
I would suggest you to completely uninstall the touchpad driver and reinstall it. Kindly follow the below given steps.

1. Press “Windows key + X” and click on “Device Manager”.
2. In the list of devices, you should see the touchpad drivers.
3. Right click on the device and then select "Uninstall".
4. In the uninstall dialog, make sure you select the option to delete the driver package from the system. This causes the driver package installed earlier to be deleted.
5. In the Action menu of Device manager, select “Scan for Hardware changes” option. This will cause the device driver to be reinstalled. Once the driver is installed, close all windows and restart the computer.
