The biggest foe of ever PC’s memory is the memory leak. There are a lot of reasons for leaking memory, but the most common one is a programming oversight.

We’ve prepared a high variety of solutions that will help you to prevent memory leaks from occurring again. There could be various factors involved, and we’re going to address most of them.

What are memory leaks in Windows?

Memory leak stands for RAM memory loss in Windows, caused by a program or an app.

Every running process in Windows is taking a certain amount or RAM. The problem is completely software-related.

There are programs that are more demanding and require more RAM usage to run properly, like Google Chrome, or Adobe Photoshop, and there are less demanding programs, that actually take smaller amounts of memory.

So, when a program is taking more memory than it should be taking, we call that a memory leak.

What is RAM memory, and how programs use it?

RAM (Random Access Memory) is a relatively small amount of memory that stores data from the running processes.

Programs store data in RAM temporarily, actually only while running. So, when you restart your PC, RAM is being emptied. Each program stores its own information about running in RAM.

As programs are different, the more-demanding ones, and the programs that actually do more complex action store more data in RAM, and therefore require more memory, while the simpler programs use less memory.

How can I fix memory leaks in Windows 10?

1. Restart your PC

  1. Press CTRL + SHIFT + ESC keys to open Task Manager.
  2. Head over to the Processes tab, and see which program is using the most memory.
  3. Just click End process, to close that program.

The program is now closed, but the problem isn’t solved yet, because the amount of memory initially requested by that program is still unavailable to other processes.

The best solution for that is to simply restart your PC, and memory leak won’t appear until you open the troublesome program next time.

RAM only stores data of running processes while the PC is turned off. Therefore, when you restart your PC, RAM will get empty, and the memory leaking problem will wipe away.


2. Use the Windows 10 built-in tools

  1. Go to Search, type Memory Diagnostic Tool and open it.
  2. Choose Restart now and check for problems and don’t forget to save your work before restarting.

Windows 10 has its own, built-in diagnostic tools that’s often enough for providing accurate analysis that will help you determining the cause of your problem.

This type of tools scans your PC for potential memory issues, including memory leaks, and gives you precise diagnostics about all detected problems.

  1. Go to Search, type Resource Monitor and open it.
  2. It allows you to view real-time data about your system.

3. Check for driver updates

  1. Go to Search, type Device Manager, and open it.
  2. Check any driver that has the yellow exclamation mark sign next to it.
  3. Right-click on it, and choose Update driver software…
  4. Follow on-screen instructions from the wizard.

Outdated drivers can be a cause to various problems in Windows 10, including memory leaks.

While an outdated driver doesn’t necessarily have to affect any program, and therefore cause memory leak, it itself can use more memory than it should.

But, if you don’t know which driver exactly should be updated, checking each driver individually is too much work. So, you should try some other method for updating drivers in Windows 10.

DriverFix automatically update drivers

We strongly recommend the DriverFix tool to update your drivers in order to avoid the permanent damage to your PC by manually downloading the wrong driver versions.

Once installed, this great tool will check your installed driver versions against its cloud database of the latest versions and will download the updates automatically.

All you need to do is wait for the scan to complete.

Keep in mind that updating your drivers is an advanced procedure. If you’re not careful, you can cause permanent damage to your system by downloading the wrong driver versions.

However, we recommend you to download this driver updater tool (100% safe and tested by us) to do it automatically. Thus, you will prevent memory leak and even permanent damage to your PC.
