If you have checked all utilities and gone through all the worst-case scenarios, and still facing the problem of slow running device, then possibly it is the system and compressed memory disk that creates the problem. The disk usage may be too high that other programs are not able to run appropriately. This article will explain 100% disk usage, the reasons causing it to happen along with quick-fix methods to solve it.

System and compressed memory disks have everything to do with the OS and memory of computer. It maintains the compression of files and folders and checks for an appropriate data flow and storage on RAM. It normally consumes little space on the CPU. However, if the disk is corrupted or damaged, it will suck on the space making other programs run slow. In that case, It may consume up to 50% or even 100% of the disk space.

As a result, you would experience reduced computer speed and performance, ultimately leading to system crash and data loss. This article briefly explains the system and compressed memory using 100% disk along with solutions to deal with windows 10 system and compressed memory high disk usage. Here are the topics that would be discussed in detail.

Overview of Windows 10 100% Disk Usage

As mentioned above, being a utility to deal with the system and compressed memory of the device, this system, and compressed memory disk is responsible for the compression of files and folders for storing them on the device. It also deals with RAM management. Though performing commendable functions with a little space consumption, the system and memory disk sometimes consumes up to 100% disk space. This portrays the underlying issues that cause this unusual consumption. Here are two of the reasons that may end up in this issue:

1. You have mishandled the virtual memory settings and changed the paging file size from automatic to a particular set value.
2. It is the system and compressed memory process itself causing the trouble. If it is the process, then using additional physical storage is not recommended.

In both cases, your device will run at a reduced speed in a way making it difficult for other programs to work on the device. As a result, you may confront freeze or crashed systems leading to data loss.

5 Methods | Fix Windows 10 100% Disk Usage

If the system and compressed memory high disk usage is a matter of concern for you, then in this section, you would get appropriate quick-fix methods that would help you to resolve the system and compressed memory using 100% disk issue. Let's get started!

1 Check your computer for malware

If you are confronting any issue like the system and compressed memory using a 100% disk, there may be an underlying virus or malware. In the best possible interest, check your device for such errors and remove them to resolve the issue. Here are the steps:

Step 1: Start the process by downloading and then installing the antivirus software.

Step 2: Once installed, launch the software and undergo a full scan of your device to check all the vital threats imposed on your computer.

Step 3: As all the threats are cleared, now restart your device and check the system and compressed memory high disk usage.

If the disk usage gets back to normal, it means a virus or malware was causing the issue. In case, if the disk is still using 100%, then head towards the next solution.

2 Set the paging file size for all drives back to automatic

If a virus or malware is not the reason, then possibly it is the paging file size with higher values causing the system and memory disk to consume 100% of the disk space. If you are using windows 10, then by default, the value for paging file size is set to automatic. In case the value is set to any custom numeral, it would hider the process of file/memory compression and lead to the problem i.e. system and compressed memory using 100% disk. Hence, setting this value back to automatic would resolve the issue. Here are the steps:

Step 1: In the main menu of Windows 10, select the option of settings, and in the settings window, search for the option of performance.

Step 2: In the next window, click the option to Adjust the appearance and performance of Windows.

Step 3: In the performance window, select the option of advanced followed by clicking on the change button present under virtual memory.

Step 4: In the virtual memory window, check the box present beside automatically manage paging file size for all drives and click ok to proceed.

Step 5: In the next window, click ok to initiate the restart.

As the device restarts, the issue would be resolved and now the system and compressed memory disk won't consume 100% of disk space.

3 Try to disable the Superfetch service

Another method that could be employed is to decrease the space consumption by system and memory disk via disabling the superfetch service. It is the utility that decreases the boot time required to load the programs with the operating system. You can disable it via run command or with a command prompt. Here are the steps to follow:

Disable Superfetch with "Run: Command

Step 1: Press Windows key + R simultaneously to launch the run dialogue box. Once launched, type services.msc command in the box.

Step 2: Now find the super fetch utility in the search box.

Step 3: In the next prompt, edit the superfetch under the option of property.

Step 4: In the superfetch services, click stop. A warning message would appear i.e. Superfetch to be disabled. Click ok to complete the action.

Disable Superfetch with Command Prompt

Command prompt can also help to resolve the issue of system and compressed memory high disk usage. Here are the steps:

Step 1: In the main menu of Windows 10, look for the command prompt, right-click on it to open. Launch the command prompt with administrative privilege. Click ok to proceed.

Step 2: In the next command prompt, type net.exe stop Superfetch. Press enter to continue.

Step 3: Wait for a while and then check the device performance.

In case if you want to check the disk, you can type chkdsk.exe /f /r in the command prompt and click enter to complete the action.

4 Optimize the visual effects for best performance

Optimizing the visual effects for best performances can also work in favor to settle the problem. Here is how you can do it.

Step 1: Press Windows key + R to launch the Run dialogue box.

Step 2: In the dialogue box, type sysdm.cpl and click enter to continue.

Step 3: Head towards system properties and select the option of advanced.

Step 4: In the next window, click the option of settings under the section of the performance.

Step 5: Now in the section of visual effects, check to adjust for best performance. Select apply and click ok to continue.

Step 6: Now reboot your device and check if the system and memory disk is consuming 100% of disk space or not. If not, the issue is resolved.

5 Check for RAM failure

Sometimes, the issue is not due to any virus or malware attack rather it is due to RAM failure. In this regard, you can check by replacing the sticks of RAM one by one. Once replaced, boot your device. This will indicate the faulty stick of RAM causing the issue of system and memory disk consuming 100% of disk space. If there are multiple sticks of the RAM, it is only one of the sticks causing the problem.

Conclusion

Hence, next time when your device is running slow, you must know, it is because of the system and memory disk creating the problem. It is the disk that deals with the system and memory management and performs the function of file and folder compression to be saved on the device. But sometimes, due to virus or malware attack or due to increased value of paging file size, the system and memory disk consumes 100% of disk space and troubles other programs, and makes it difficult to run on the device. This article explains the issue in detail along with some built-in quick fix mechanisms to solve the problem i.e. system and compressed memory using 100% disk.
