High disk usage Windows 10 is a common but serious computer issue. Luckily, this problem can be resolved possibly. This article aims to teach you how to lower the disk usage in Windows 10 with 8 effective ways.
A 100% disk usage issue on your computer can be frustrating and can lead to slow performance and unresponsiveness. Several factors can contribute to this problem, and it's essential to diagnose the specific cause to address it effectively. Here are some common reasons for high disk usage Windows 10:
◤Background processes: Sometimes, background processes or services can use a significant portion of your disk's capacity.
◤ Windows update: Windows updates can sometimes trigger high disk usage, especially during the update installation process.
◤ Malware and viruses: Malware or viruses can also cause high disk usage. Ensure that your antivirus software is up to date and run a full system scan to remove any potential threats.
◤ Driver issues: Outdated or incompatible device drivers can lead to disk usage problems. Make sure your drivers are up to date, especially for your hard drive or SSD.
◤ Disk fragmentation: Over time, your disk may become fragmented, which can lead to slow performance and high disk usage.
◤ Insufficient RAM: If your computer has limited RAM, it may resort to using the disk as virtual memory, which can lead to high disk usage. Consider upgrading your RAM if you frequently encounter this issue.
◤ Faulty hardware: In some cases, a failing hard drive or SSD can lead to high disk usage. You can check for disk errors and health using the built-in Windows tool called "Check Disk" or third-party disk health monitoring software.

If you find that none of the above solutions solve the high disk usage Windows 10, then upgrading your current small hard drive to a larger one, especially an SSD (Solid State Drive) can provide a comprehensive solution.
SSDs can significantly improve load times and efficiently handle multiple concurrent tasks and processes without sacrificing performance. A key strategy is to run the operating system on an SSD while retaining the old HDD as a secondary storage drive, which helps reduce stress on the HDD. However, you may be wondering how to perform this upgrade process smoothly.
For this purpose, we recommend using AOMEI Partition Assistant Professional. This powerful tool allows you to upgrade your hard drive without completely reinstalling everything. It does this by cloning everything from one disk to another and ensuring that the operating system and other programs can boot successfully from the cloned disk. You can start by downloading the demo version to explore its features and evaluate whether it suits your specific needs.
Step 1. Install and launch AOMEI Partition Assistant, click "Clone" in the main interface and select "Clone Disk".
Step 2. Choose the hard disk that you need to clone as the source disk and click "Next".
Step 3. Select the destination disk to store the data on the source disk, and then click "Next".
Step 4. Then, you can check the source and destination disk in the next window or change to “Sector to Sector clone”, and click the "Confirm" button to continue if there is no problem.
Here, you can also click the "Settings" button to adjust the partition size on the destination disk or tick "4k alignment" to improve the reading and writing speed of SSD if the target disk is an SSD drive.
Step 5. At last, click "Apply" and "Proceed" in the main interface to start cloning the hard drive.
How to lower the disk usage in Windows 10? For addressing this issue, the eight methods outlined are all viable solutions worth exploring. However, the last method, which involves upgrading to a larger SSD and utilizing AOMEI Partition Assistant Professional, is particularly recommended for achieving optimal results.
