7 Essential Windows Disk Cleanup and Optimization Tips Every Windows User Should Know

Keeping your Windows PC running smoothly requires regular maintenance, especially when it comes to disk cleanup and optimization. Over time, your computer can accumulate unnecessary files, fragmented data, and other clutter that slows performance. Here are seven essential disk cleanup and optimization tips, complete with practical steps you can follow—regardless of your technical skill level.

Why Is Disk Cleanup Important?

Regular disk cleanup helps prevent sluggish performance, system errors, and even crashes. By removing junk files and optimizing storage, you extend your hard drive’s lifespan and improve your PC’s overall speed.

1. How Can I Remove Temporary Files Safely?

Windows stores temporary files that may be left over from installations, updates, or browsing. Here’s how to delete them:

Step 1: Press Windows Key + R to open the Run dialog.
Step 2: Type %temp% and press Enter.
Step 3: Select all files in the folder (Ctrl + A) and press Delete. Skip any files that are in use.

For a more comprehensive cleanup, use Glary Utilities’ Disk Cleaner tool. Open Glary Utilities, click on “Advanced Tools,” and select “Disk Cleaner.” This scans for temporary files system-wide and safely removes them.

2. What Is Disk Cleanup and How Do I Use It?

Disk Cleanup is a built-in Windows tool that removes unnecessary files.

Step 1: Press Windows Key, type Disk Cleanup, and select the app.
Step 2: Choose the drive you want to clean (usually C:).
Step 3: Select the file categories to delete—like temporary files, system files, Recycle Bin, and thumbnails.
Step 4: Click OK, then Delete Files.

For even more cleaning options, Glary Utilities offers a “1-Click Maintenance” feature that scans and removes system junk, invalid shortcuts, and more with a single click.

3. How Do I Uninstall Unused Programs?

Unused programs take up valuable space and resources. Here’s how to remove them:

Step 1: Open Settings (Windows Key + I).
Step 2: Go to Apps > Installed apps or Apps & features.
Step 3: Browse the list, click on any program you no longer use, and select Uninstall.

Glary Utilities offers an enhanced Uninstall Manager that not only removes programs but also cleans up leftover files and registry entries for a cleaner system.

4. Can Managing Startup Programs Make My PC Faster?

Too many startup programs can slow down boot times. To manage them:

Step 1: Press Ctrl + Shift + Esc to open Task Manager.
Step 2: Go to the Startup tab.
Step 3: Right-click on programs you don’t need at startup and select Disable.

Glary Utilities’ Startup Manager provides an easier interface to view, manage, and delay startup items for even faster boot times.

5. How Do I Defragment My Hard Drive?

Fragmentation can slow down file access on traditional HDDs. Here’s how to defragment:

Step 1: Press Windows Key, type Defragment and Optimize Drives, and open the app.
Step 2: Select your drive and click Optimize.

Note: SSDs do not require defragmentation, but optimization is still helpful.

Glary Utilities includes Disk Defrag, which provides a user-friendly way to defragment and optimize your drives for maximum speed.

6. Why Should I Empty the Recycle Bin Regularly?

Files in the Recycle Bin still take up disk space. To empty it:

Step 1: Right-click the Recycle Bin on your desktop.
Step 2: Click Empty Recycle Bin and confirm.

Glary Utilities can automatically include the Recycle Bin in its cleanup routines, saving you the step.

7. How Can I Run a Full System Clean Automatically?

Manual cleanup is good, but scheduling regular scans is better.

Step 1: In Glary Utilities, go to “Schedule Tasks.”
Step 2: Set up automated cleanups for junk files, registry errors, and more at intervals that suit you (daily, weekly, etc.).

This keeps your system clutter-free without constant manual intervention.

Final Thoughts

Regular disk cleanup and optimization are key to keeping your Windows PC efficient and reliable. By following these seven tips—and using a comprehensive tool like Glary Utilities—you can ensure your system stays fast, stable, and ready for anything. Whether you’re a beginner or an advanced user, adopting these habits will help your computer run like new.
