Power users can clear the computer cache faster using command line tools. Launch Command Prompt as admin. To do so, press Windows + X and select Command Prompt (Admin) or Terminal (Admin) from the menu. Then, execute the commands below, and don’t forget to restart the PC afterward.

Please close all apps before clearing the cache. Active apps might break when trying to access deleted cache data. Windows rebuilds the necessary cache files automatically after cleanup. For best results, run basic cleanups monthly and system file cleanups quarterly. You’ll notice faster boot times, quicker app launches, and smoother system performance.

Clearing the Browser Cache

If your web browser is slow, it doesn’t load fresh web content, or your browsing experience is marred by unresponsive behavior, it must be due to a corrupt cache. Web browsers like Chrome, Safari, Edge, Firefox, and Opera pile up cache files on your PC. Clearing the browser cache and cookies will make your browser perform faster.

Edge and Chrome browsers store everything from browsing history to downloaded files. Here’s how to clear the browser cache:

  1. Press Ctrl + Shift + Delete to open browsing data settings
  2. Pick your time range
  3. Select items to remove:
    • Browser history
    • Download history
    • Cookies and site data
    • Cached files
    • Saved passwords
    • Form data

Websites load fresh content after cache clearing. First visits might feel slower while browsers build a new cache.

Fix DNS and Network Cache Issues

DNS and network cache problems break your internet connection, causing slow speeds or complete disconnects. Let’s check out the fastest ways to clear these caches and restore your network performance.

1. Clear DNS Cache

DNS cache saves website IP addresses for quick access. However, outdated or corrupted records may cause the following problems.

  • Website access fails
  • Network security alerts
  • Slow browsing
  • DNS update delays

Clear DNS cache using these steps:

  1. Hit Windows + R.
  2. Type cmd in the Run box.
  3. Enter ipconfig /flushdns and press Enter.
  4. Check the success message.

Regular DNS cache clearing stops DNS poisoning attacks. Hackers use these attacks to inject fake DNS records, sending you to malicious sites. Besides, there are 5 other ways to flush the DNS cache in Windows 10 and 11.

2. Reset Network Settings

Network reset fixes stubborn connection problems by removing and reinstalling network adapters. Before you proceed with the reset, do not forget to write down network settings and save Wi-Fi passwords.

To reset network settings on Windows 11, do the following:

  1. Open Settings and select Network and Internet.
  2. Pick Advanced network settings.
  3. Select Network Reset.reset network settings in windows 11 via settings
  4. Hit Reset Now.

On Windows 10, launch Settings and navigate to Network & Internet > Status and select Network reset.

A network reset changes these components:

  • Winsock: Handles internet I/O
  • TCP/IP: Controls device communication
  • Network adapters: Physical/virtual interfaces

You’ll need to set up these again:

  • Wi-Fi connections
  • VPN profiles
  • Custom IP settings
  • Network drives

Use network reset as your last option after basic fixes fail. When done right, it solves complex network issues.

Setting Up Automatic Cache Cleanup

Windows cache settings need proper tuning for peak performance. Smart cache configuration prevents system slowdowns and keeps your PC running smoothly. Storage Sense handles automatic cache cleaning in Windows. The tool watches system resources and removes unneeded files based on your rules. Set up auto cleanup:

  1. Launch Settings.
  2. Go to System > Storage.
  3. Turn on Storage Sense.
  4. Pick cleanup times:
    • Temp files removal
    • Old downloads cleanup
    • Recycle bin emptying

Windows checks drive space and clears the cache automatically to maintain size limits. This stops cache problems without manual work.

Different cache types need different cleaning approaches. System cache, browser data, and DNS records affect your PC’s performance. Storage Sense and PC Manager handle automatic cleaning while manual cleanup tackles stubborn issues. I’ve been testing various cache-cleaning schedules on my Windows PC, and monthly basic cleanup with quarterly deep cleaning works best. This keeps performance high while preserving quick access to frequent files.
