How To Free Up Space On Windows 10: Quick Cleanup for Faster Performance

My Windows 10 laptop slowed to a crawl last month. Turns out 60GB of junk files were hogging the drive. The fix took 20 minutes and restored it to factory speed.

Disk Cleanup and Storage Sense handle most of the heavy lifting. I run them monthly now—no special tools, just built-in Windows utilities doing exactly what they should.

You’ll reclaim 10-30GB typically, with noticeable improvements in boot time and app launches. The process is idiot-proof if you follow the steps in order.

Works on any Windows 10 machine, old or new. Here’s how to start the cleanup.

What Youll Need

Instructions

Here’s the process I use to reclaim gigabytes of storage and speed up a sluggish system.

Open the Start menu, type Disk Cleanup, and select the utility. Choose your C: drive when prompted. The tool scans for temporary files, system caches, and old Windows updates that are safe to delete.

Check all boxes in the list—especially Temporary files, Downloaded Program Files, and Windows Update Cleanup. Click OK and confirm deletion. This alone often frees 5-10GB on a typical system.

Wait for the process to complete. You’ll see a progress bar, and the utility will disappear once finished. No reboot is required at this stage.

Browsers accumulate massive caches over time. In Chrome, press Ctrl+Shift+Delete, select All time as the range, and check Cached images and files plus Cookies and other site data. Click Clear data to remove 1-3GB of clutter.

Navigate to your Downloads folder next. Sort by date and delete any old installers, archives, or files you no longer need. I’ve seen users reclaim 15GB+ from this folder alone after years of accumulation.

Open Settings, go to Apps > Apps & features, and sort by size. Look for large applications you haven’t used in months—old games, trial software, or bloated suites. Select the app and click Uninstall.

Pay special attention to manufacturer bloatware like preinstalled trial software or duplicate media players. These often consume hundreds of MB to several GB each. The uninstall process may take 1-2 minutes per application.

In Settings > System > Storage, toggle Storage Sense to On. Click Configure Storage Sense and set it to run every day during off-hours. This automatically deletes temporary files and empties the Recycle Bin.

Under Temporary Files, check Delete temporary files that my apps aren’t using. For the Recycle Bin, set it to delete files after 30 days. This prevents permanent loss while keeping storage lean.

Storage Sense works in the background, so you won’t notice it running. The first cleanup may free 1-5GB immediately, with ongoing savings as it maintains the system.

Tips and Common Mistakes

Simple adjustments that prevent wasted effort and maximize every cleanup step.

Disk Cleanup Deep Dive: In Step 1, don’t just check the obvious boxes—scroll through the entire list. I’ve found that Windows Update Cleanup alone can free 5-10GB on systems with years of updates. The scan might take a few minutes, but it’s worth the wait for that storage boost.

Browser Cache Reality Check: For Step 2, clearing All time in Chrome isn’t just about space—it also resolves weird website behaviors. Between us, I once had a site crash repeatedly until I cleared cookies and cache. The 1-3GB you reclaim here adds up fast across multiple browsers.

Uninstall Strategy: During Step 3, sort by size first, but also check the Install date column. Applications you installed years ago and never use are prime candidates. Those 1-2 minutes per uninstall pay off when you’re reclaiming hundreds of MB to several GB from bloatware.

Storage Sense Optimization: In Step 4, don’t just set it and forget it. I configure Storage Sense to run every day but adjust the Recycle Bin setting to 14 days instead of 30 days—it’s a balance between safety and space. The first run often surprises users with 1-5GB freed immediately.
