How To Fix High RAM Leakage and High CPU Use of Windows 10 Run PC/Laptops caused due NTOSKRNL Process

If you are using a Windows 10 run PC or laptop you may have already encountered this problem.

Several Windows 10 users have reportedly been complaining on Reddit and Microsoft Forums about unexpected memory leaks pertaining to system processes like ntoskrnl.exe and Runtime Broker, wherein an increased amount of RAM and CPU usage during PC boot ups has been extensively reported.

The issue seems to have been caused by a bug which inflates the RAM and leaks memory in the process. During a normal process when you are not using many Apps, your PC/laptop should use around 30 percent of RAM and around 40 percent of your CPU.

However, if your Windows 10 is buggy, it can use anywhere between 80-90 percent RAM and 85 percent of your CPU causing a mild hang which can be only cured by rebooting your PC/laptop.

According to the researchers at Bidness Etc the high RAM and CPU leakage is caused by the memory leak issue which remains dormant for the first few hours of PC/laptop use, but slowly takes over all the available free memory and a large portion of the processor usage.

How To Fix High RAM and CPU Usage in Windows 10 

1. Registry Hack:

  • Hit Win Key + R
  • Type in “Regedit” and then hit Enter.
  • Go to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management’

6. Close and uninstall as many unwanted preinstalled applications as many you can

Removing malware

One of the main reasons for the slow down of your PC/laptop could be malware. One of the most common malware that infects your PC is perhaps the adware that comes from your browser.

One could employ the use of Malwarebytes Anti-malware tool or Microsoft’s native Windows Defender.

Both the software offer a comprehensive scanning and cleaning mechanism to eradicate spyware and malware infections.

Just run the complete scan or deep scan to remove any malware infection and reboot your PC to get rid of any infection.

If the issue still persists, you can move on to the next step by updating outdated or faulty drivers.

Updating outdated or faulty drivers

Several users have reportedly claimed that outdated or faulty drivers are the main reason behind this potential memory leak issue in Windows 10.

Although Microsoft has rolled out automatic driver updates for all known hardware installed on the PC, it may not be fully optimized for the best performance. Hence, it is imperative to download the latest drivers from the OEM or hardware vendor to plug the high memory and CPU usage problem.

The most basic drivers are sound, graphics, and network drivers, which are often the root cause of memory leaks as reported by several affected users, following the Windows 10 upgrade.

  1. The best way working so far for me is stopping superfetch process as it uses. 100% disk and makes computer slow

    Just open cmd as administrator and type
    Net stop superfetch

    I’ve found this most useful trick so far

  2. Hi

    I have tried all the above tips (except the registry tweak as my laptop doesn’t have an entry ‘ClearPageFileAtShutDown’ in memory management) to no avail.

    My 8Gb HP Pavilion becomes basically unusable after about 30 minutes as Ram usage climbs from 30% at re-start to 94%. No apps are running, the machine is just idling. Understandably, I’m fed-up with having to re-start my laptop every 30 minutes.

    Any other suggestions?

  3. Kevin Keys try to look in:
    Hkey_local_machine / System / CurrentControlSet / Control / Session Manager / Memory Management
    And then look on the right for CleatPageFile…

  4. my laptop 1 GB RAM and core 2 duo 2.0 g.Hz processor but my CPU and RAM usage 100% and play tekken 3 GTA San very slow

    • It seems like your computer is a bit outdated. If you can afford a new computer, I would definitely do it. Only lightweight Linux-Based OS’s can run with 1GB of RAM, and frankly, a dual core processor at 2.0 GHz is not going to run GTA (or any other games for that matter!).

  5. I have that problem too. When my Laptop is on standby and there is no running application after 30 minutes the ram usage went hight up to 80%-85% but when I monitored the ram usage in the task manager and keeps it running in background I noticed that the ram usage is stable and just around 42%-48%. So whenever I am using my laptop I always run the taskmanager on back ground and thus solved my high ram usage problem but I want to know why the ram went up without application running. I also tried some solution that could fix the problem but nothing works.

  6. I literally just bought this PC today. its brand new, all hardware on it is dated to this year. pretty sure outdated drivers arent the issue. windows 10 just fucking sucks

  7. !Caution! Step #3 rely screwed up my PC!

    My screen ended looking like Windows 98SE.
    I change back to undo Step #3 Now it looks
    OK.

    Still doesn’t fix the run-a-way CPU issue!

  8. Settings/Privacy/General (change privacy options/ turn All OFF
    Settings/Privacy/Windows Permissions/ turn All OFF
    Settings/Privacy/App Permissions/ turn All OFF
    Restart your PC

  9. If you have a lower end computer with limited resources, it may be time for an upgrade. I would recommend spending at least $150 on a PC, even used. Make sure that the latest software and OS’s can run on it, such as a computer with 4+ GB’s of RAM, and at least a Dual-Core i5.

  10. For all you developers and people with high-end hardware, try making sure that any Hyper-V Machines are not in the ‘Running’ state. Even though it may seem inactive, an updating Ubuntu system can consume 6GB of RAM without your knowledge.
