PC • DAILYTECH.ID - A slow PC is often caused by accumulated cache and temporary files that build up over time. If your system feels laggy or storage is running low, learning how to clear cache on Windows 10 can quickly improve performance without installing additional software.

To clear cache on Windows 10, go to Settings > System > Storage > Temporary files, select the files you want to remove, and click Remove files. You can also use Disk Cleanup or the Run command to delete cache instantly.

In this guide, you’ll learn how to clear cache on Windows 10 step by step, including system cache, app data, browser files, and RAM to keep your PC running fast and smooth.

What is Cache on Windows 10 and Why It Slows Down Your PC

Cache on Windows 10 is temporary data stored by the system, applications, and browsers to help speed up processes and reduce loading times. This includes files like thumbnails, system logs, update data, and browsing history that allow your computer to respond faster during repeated tasks.

However, as cache builds up over time, it can take up significant storage space and start affecting performance. Instead of improving speed, outdated or corrupted cache can lead to system lag, app errors, and slower overall performance, making it important to clear cache regularly.

How to Clear Cache on Windows 10 (Step-by-Step)

Clearing cache on Windows 10 involves removing different types of temporary data stored by the system, applications, and browsers. These files are created to speed up performance, but over time they can pile up, take up storage space, and even cause system slowdowns or errors.

By following the methods below, you can target each type of cache and clean your PC more effectively. This helps improve speed, free up disk space, and keep your system running smoothly without unnecessary files.

1. Clear Cache Using Disk Cleanup

Disk Cleanup is one of the most effective tools for removing system-level cache, including Windows update files, temporary installation data, and other hidden files that can consume several gigabytes of storage.

Steps:

• Search Disk Cleanup in the Start menu
• Select your main drive (C:)
• Click Clean up system files
• Select items like Windows Update Cleanup
• Click OK → Delete Files

2. Clear Temporary Files via Settings

This method uses the modern Windows Settings interface, making it easier for beginners to identify and remove unnecessary files. It also provides a clear breakdown of what is taking up space on your system.

Steps:

• Open Settings
• Go to System > Storage
• Click Temporary files
• Select the files you want to remove
• Click Remove files

You can also enable Storage Sense to automatically clear temporary files and prevent future buildup.

3. Clear Cache Using Run Command

Using the Run command allows you to directly access hidden system folders where temporary files are stored. This method is faster and helps remove leftover cache that may not appear in standard cleanup tools.

Steps:

• Press Win + R
• Type %temp% → delete all files
• Type temp → delete all files
• Type prefetch → delete all files

4. Clear DNS Cache on Windows 10

DNS cache stores information about websites you’ve visited to speed up future access. However, outdated or corrupted DNS data can cause connection issues or prevent websites from loading properly.

Steps:

• Open Command Prompt as administrator
• Type ipconfig /flushdns
• Press Enter

5. Clear App Cache on Windows 10

Many applications store local cache files such as images, scripts, and logs to improve loading speed. Over time, these files can become too large or corrupted, leading to lag, crashes, or unexpected errors.

Steps (Discord):

• Press Win + R
• Type %appdata%
• Open the Discord folder
• Delete Cache, Code Cache, and GPUCache

Steps (Roblox):

• Go to %localappdata%\Roblox
• Delete Downloads and Logs

6. Clear Browser Cache on Windows 10 (Chrome)

Browser cache stores website data such as images and scripts to load pages faster. However, too much cached data can slow down your browser and cause outdated content to appear.

Steps:

• Open Chrome
• Press Ctrl + Shift + Delete
• Set time range to All time
• Check Cached images and files and Cookies
• Click Clear data

7. Clear RAM Cache on Windows 10

RAM cache (also known as standby memory) is used to store frequently accessed data for faster performance. In some cases, Windows may not release this memory efficiently, which can affect performance during heavy tasks.

Steps:

• Restart your PC (fastest method)
• Or use RAMMap → select Empty Standby List

How Often Should You Clear Cache on Windows 10

For most users, clearing cache on Windows 10 every 1 to 3 months is enough to maintain good performance. Temporary files build up naturally over time, but they don’t need to be removed too frequently unless you notice slowdowns or low storage space.

If you use your PC for gaming, video editing, or other heavy tasks, clearing cache once a month can help keep your system running smoothly. You can also enable Storage Sense to automatically remove temporary files and reduce the need for manual cleanup.

• Uninstall unused applications that may store unnecessary data
• Keep Windows updated to benefit from performance improvements and bug fixes
