Hi guys,
I have the same issue after update, took a month tried every suggestions from MS agents, advisors and moderators with no luck. My laptop randomly stuttering 2-3 times a day from using Movies & TV on big screen through HDMI, until
I did one method that seems to mitigate or at least I can enjoy movies without saying bad word 3 times a day.
To understand windows lag and stuttering you have to go all the way back to 2013;
And the most recently ;
After much research, I found that the most complaints are these two processors that may have contributed to the problem. ACPI that related to Battery and Adjusting the clock speed of the CPU. Also called "dynamic frequency scaling," CPU throttling.
And NtOsKrnl that is Windows NT kernel and nothing you can do to tame it unless Microsoft takes their head out of the sand.
Here’s the tool I’m using “LatencyMon” to monitor what’s going on behind my back;
And here’s the software that at least blocks most of the things that shouldn’t be running without your permission, “O&Oshutup10”;
Long story short...
1) I updated from 1709 to 1803 build and that where lag and stuttering begins
2) Rollback to the original image my laptop is perfectly fine again
3) Update again to 1903 randomly stuttering came back
(Note: Reset or Clean install doesn’t do any good both times. ACPI and Ntoskrnl are the pc killer)
Following are the method I mentioned;
4) Barebones install 1809 (From Microsoft ISO download site) which of causes, bunch of unknown device shows up in device manager. But I choose to update only 2 drivers..
- Displays driver
- Sound Drive (Realtek)
Then
- Install Shutup10 to limits most of background
- Turn off Background Apps in setting
- Turn off all Setting/Privacy
- Turn off all Setting/Gaming
- Turn off SaveMode when Battery below 20% (Only apply to laptop. this is where stuttering most occurs)
- Set network status to “Meter” preventing update
- Disable Windows Automatic update in Group Policy (Windows 10 pro) or “wuauserv” in Services
- Disable all enhance audio from Realtek’s property (KMplayer has its own internal codec)
- increases Pagefile to double the size where windows recommended (not to exceeding ram size)
- I’m using The KMplayer instead of Movies & TV (MS Movies players from my observation might have corrupted memory and/or search index when stuttering happens. When that happens, don’t restart. Instead, force shut down by holding
power button)
Then to ensure that my system is up to the task, I did the following..
5) Run Windows PowerShell (Admin)
type sfc /scannow
If corrupted files found and couldn’t be fixed then use
DISM.exe /Online /Cleanup-image /Restorehealth
To rebuild package then Run sfc /scannow again (1903 came with corrupted defenders security)
6) Lastly run Setting/Security and update/trouble shoot on compatibility and search index. (I found one of the Realteks Dll incompatible, has to set as Windows 8)
Words of caution;
Do research and understand any and all of these procedures before you start. It works for me, might not work for you. Keep in mind, install fresh Windows means you will lose every programs you previously installed and without proper
drivers, you might lose some hardware functionality)
Hope my experiences help.
