How to solve win11 memory leak. Analysis of the causes of win11 memory leak and various solutions.

php editor Xiaoxin will analyze the memory leak problem of win11 for you. Memory leaks may be caused by a variety of reasons, such as program bugs, unreleased resources, etc. Solutions include updating system patches, closing programs that may cause memory leaks, using memory management tools, etc. By analyzing the causes and taking effective measures, you can effectively solve the win11 memory leak problem and improve system performance and stability.

Causes of memory leaks:

Memory leaks are caused by misalignment of resources in computer programs due to incorrect memory allocation. This happens when unused RAM locations are still not freed. Don't confuse memory leaks with space leaks or high memory usage, which is when a program uses more RAM than it needs. The memory leak on Windows 11/10/8/7 systems allegedly occurs when the memory is unused but inaccessible.

Why memory leaks are bad:

A memory leak is bad because it is a bug, a flaw in the operating system or software. But let's see how exactly it affects the system:

• This results in memory exhaustion since the memory is not released even when it is not used.
• Exhausted memory causes software to age.
• Reduced available memory can result in increased response times and reduced system performance.
• Unchecked memory leaks may eventually cause the application to crash.

In order to identify a memory leak, a programmer needs access to the program's source code.

How to locate memory leaks

To solve a problem, we need to identify it first. The basic steps to locate a memory leak are:

• Affirmation : Determine whether a leak has occurred.
• Find kernel-mode memory leaks: Locate leaks caused by kernel-mode driver components.
• Find user-mode memory leaks: Locate leaks caused by user-mode drivers or applications.

How memory allocation happens

There are different modes for applications to allocate RAM. If space is not released after use, a memory leak can occur regardless of the allocation mode. Some common allocation patterns are:

• HealAlloc function is used for heap memory allocation. The C/C runtime equivalents are malloc and new.
• VirtualAlloc function for direct allocation from the operating system.
• Kernel32 API for saving application kernel memory. For example, CreateFile, CreateThread.
• User32 API and Gdi32 API.

How to Prevent Memory Leaks in Windows

We all know that prevention is better than cure, so it is important to monitor your system.

You need to pay attention to whether various programs and applications use RAM abnormally. You can go to Windows Task Manager by pressing CTRL SHIFT ESC and add columns for handles, user objects, GDI objects, etc.

This will help you monitor resource usage easily.

Microsoft tools to diagnose memory leaks

Various tools diagnose memory leaks in various allocation modes:

• Application Verifier diagnoses heap leaks.
• UMDH (a component of Debugging Tools for Windows) analyzes leaks in individual processes by monitoring heap memory allocations.
• Trace Capture is used to comprehensively analyze RAM usage.
• Xperf also tracks heap allocation patterns.
• CRT Debug Heap not only tracks heap allocations but also enables coding practices to minimize leaks.
• JavaScript Memory Leak Detector Debug memory leaks in your code.

Usage Tips

• Use kernel HANDLE and other smart pointers for Win32 resource and heap allocation.
• Get automatic resource management classes for kernel allocation from the ATL library. The C standard has auto_ptr for heap allocation.
• Encapsulate the COM interface pointer in a "smart pointer" with the help of _com_ptr_t or _bstr_t or _variant_t.
• Monitor .NET code for unusual memory usage.
• Avoid multiple exit paths from functions so that allocations are freed from variables in most blocks when the function ends.
• Use native exceptions only after all allocations in the _finally block are freed. Wrap all heap and handle allocations into smart pointers to use C exceptions.
• Always call the PropVariantClear function before reinitializing or discarding a PROPVARIANT object.

How to Fix Memory Leak in Windows 11/10

Just like the various ways to prevent memory leaks, there are also various ways to stop memory leaks. But before you start, remember to create a system restore point first.

1]Close the process and restart

If you see an unnecessary process taking up too much RAM, you can end the process in Task Manager. You will need to reboot the device so that the freed space can be used by other processes. The memory leak problem will not be solved without restarting. Runtime Broker is a process known to slow down your PC. See if disabling that alone works.

2]Memory Diagnostic Tool

To access the built-in Memory Diagnostic Tool for Windows:

• Save all important work.
• Press Win R to open the "Run" window.
• Type the command mdsched.exe in the "Run" window.
• Restart the computer.
• After restarting, perform a basic scan or select "advanced" options such as "Test Combination" or "Pass Count".
• Press F10 to start testing.

These are still temporary fixes.

3] Check for driver updates

Outdated drivers can cause memory leaks. Keep all drivers updated. Follow one of the following methods to update your device drivers:

• You can check for driver updates through Windows Optional Updates to update your drivers
• You can visit the manufacturer's Website to download drivers.
• Use free driver update software
• If you already have the INF driver file on your computer:
  • Open Device Manager.
  • Click the Driver category to expand the menu.
  • Then select the relevant driver and right-click on it.
  • Select Update Driver.
  • Follow the on-screen wizard to complete the audio driver update.

#Updating your operating system and installed programs and Microsoft Store apps may also help.

4]Optimize performance

Tweaking Windows performance will manage everything including processor scheduling and memory usage to stop memory leaks. Follow these steps:

• Right-click "This PC" and select "Advanced" settings in the left pane.
• Under the Advanced tab, go to Performance, then Settings.
• Check "Adjust for best performance" and click "OK".
• Restart and check if the problem is resolved.

If this simple solution doesn't work, try the next solution.

5] Disable programs that run on startup

Disabling troublesome programs is the only way to get rid of memory leak problems. Go to Task Manager and disable the troublesome program. If you don't know which program is causing the problem, do the following:

• Go to Task Manager.
• Go to Startup.
• Disable startup programs that are not required to run by default.

6] Defragment your hard drive

While Windows 11/10 will do this for you automatically, you may need to occasionally defragment your hard drive to optimize performance:

• Go to This PC or My Computer.
• Right-click on the system hard drive (usually the C: drive).
• Go to Tools under Properties and select Optimize.
• Select the drive to be defragmented and select "Analyze".

Restart the computer after the new fragmentation.

7] Clear page file on shutdown

It's getting more complicated these days - but don't worry. Here's how to clear the page file every time you shut down:

• Type regedit in the search to launch the Registry Editor.
• Enter this path:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Manager内存管理

• Change the value of ClearPageFileAtShutDown to "1".
• Save changes and restart the device.

This should be done. Keep in mind that your shutdown process will take more time.

9]Disable Super Fetch

This Windows service optimizes performance by minimizing startup time. It lets Windows manage RAM usage. Life with Superfetch disabled is inconvenient, but do it if you must. At least try this alone to isolate the problem:

• Search for services.msc and go to Services Manager.
• Look for "Superfetch" and right-click on it to go to "Properties".
• Select "Stop".
• The service can also be "disabled" from the drop-down menu.
• Restart your PC and check if performance improves.

If this doesn't work, enable Superfetch.

10] Check for malware

Use third-party antivirus software or Microsoft Defender that comes with Windows to scan and remove malware. Make sure to update your antivirus software to support your operating system so it doesn't become the cause of memory leaks.

11] Modify settings

1. Click "Start" in the taskbar in the lower left corner, and enter "Control Panel" in the search box above to open it.

#2. After entering the new interface, switch the "View By" in the upper right corner to "Large Icons", and then click "Power Options".

#3. Then click "Choose what the power buttons do" in the left column.

4. Then click "Change settings that are currently unavailable" in the upper box.

#5. Finally, find “Enable Fast Startup”, uncheck the small box, and click Save Changes.

12] Modify settings

1. It may also be a memory leak caused by the graphics card driver.

2. You can choose the old version of the driver to download and install from the Intel official website.
