Dealing with temp files on Windows 10 can be kinda tedious if you’re not used to the process, but it’s one of those small maintenance tasks that actually makes a difference. Over time, these temp files pile up—created by your apps, Windows updates, or even just browsing—and if they’re left unchecked, your system can slow down or runs out of space faster than it should. The good news is, it’s pretty straightforward to clear them out, and it can give your PC a bit of a performance boost. Plus, it’s nice to see more free storage without resorting to fancy programs. Here’s how to do it using the built-in options, step by step, with some extra tips thrown in because Windows has a funny way of making things complicated sometimes.
How to Delete Temp Files in Windows 10
What’s actually happening here and when to try it?
This process helps if your PC is sluggish, running out of space, or if you just want to clean up after installing a bunch of updates or apps. When temp files build up, they can slow down disk access or even sometimes confuse the OS. Deleting them can free up storage and maybe help your system feel snappier, especially if you haven’t done it in a while. Expect to see your free space increase (obviously), and maybe a slight boost in responsiveness. Fair warning: on some setups, this might only clear a few megabytes, but still, it’s free and easy, so why not?
Method 1: Using Windows Storage Settings
This is the fastest way if you want to avoid fussing with command lines or third-party junk. It works well if you notice your PC slowing down or filling up unexpectedly. The reason it helps is that Windows tracks down the temp files and lets you pick what to delete—kind of like a mini cleanup wizard built right into the OS.
Open Settings and navigate to Storage
- Hit Windows + I to open Settings directly. If that doesn’t work, click the Start menu and then the gear icon.
- From there, click on System.
- Then select Storage from the left sidebar.
Find and clear “Temporary files”
- In the Storage overview, scroll down a bit until you see Temporary files and click on it.
- This section scans for stuff like cache files, old setup files, leftover logs, and more. It might take a few seconds to gather info.
- You’ll see checkboxes for different categories—like “Temporary Internet Files, ” “System created Windows Error Reporting Files, ” and “Temporary Files.” On some machines, you’ll also see “Previous Windows installations” if a major update was done recently.
Choose what to delete and hit Remove
- Select the checkboxes for the files you want gone. Don’t go wild deleting everything — some might be needed if you’re troubleshooting or restoring your system.
- Once you’re set, click Remove files. Windows will process and delete the selected data.
This method is super handy because it’s quick, graphical, and you get to see what’s going away. Sometimes, Windows throws in a surprise extra like “Old Windows files” or “Downloaded program files, ” which are usually safe to delete unless you’re in the middle of something important. On one setup it worked instantly; on another, I had to restart afterward for the changes to take effect. Not sure why, but Windows has to make it harder than necessary sometimes.
Method 2: Using Disk Cleanup
This classic tool is more thorough—sometimes more than Storage Settings. It’s been around forever and still does the job if you want a bit more control. Plus, it can clean other junk like system restore points or shadow copies, which can pile up unnoticed.
Run Disk Cleanup and select what to purge
- Type Disk Cleanup in the search box next to the Start menu and click on it.
- Select the drive you want to clean (usually C:) and click OK.
- Wait for the scan to finish. It will show a list of file types you can delete.
- Check “Temporary files, ” “Thumbnails, ” and “Recycle Bin” (if you’ve emptied it).Want to go deeper? Click Clean up system files—this adds more options like old update files and system restore points.
- Review and click OK to start cleaning.
Some folks swear this is the most effective method for a deep clean, especially if you’ve got a lot of system junk. On some setups, it takes a bit longer, but it’s worth it for the peace of mind.
Watch out for tricky files
Be cautious not to delete anything critical—this method’s pretty safe, but Windows does label a few files as “deleteable” that you might want to keep, especially if you’re not sure. Always double-check before hitting clean, like with historic restore points or shadow copies.
Another trick: Using Command Prompt or PowerShell
- Open PowerShell as Admin: right-click the Start menu and select Windows PowerShell (Admin).
- Type this command to delete temp files:
Remove-Item -Path "$env:TEMP\*" -Recurse -Force - For system temp files, run:
Remove-Item -Path "C:\Windows\Temp\*" -Recurse -Force
These commands really clear out temp directories at a system level. Use with caution, though. On some machines, this might fail if some files are in use, or you might need to reboot afterward.
Final notes
Whichever method you pick, remember that Windows will usually clean temp files on its own eventually, but doing it manually saves time and keeps drive clutter down. Sometimes a quick restart or a cache refresh can do wonders too if things seem slow after cleaning.
Summary
- Use Windows Storage Settings for quick cleanup
- Try Disk Cleanup for more options
- Command line tools are handy if you’re comfortable with them
- Be careful not to delete stuff you might need.
Wrap-up
Cleaning out temp files isn’t glamorous, but it’s one of those chores that can keep Windows happy and running smoother, especially if it’s cluttered. It’s kind of weird, but doing this regularly (say once a month) can prevent slowdown and free up a chunk of space. Not sure why it works, but on some machines, it’s enough to breathe new life into them. Hopefully, this shaves off a few hours for someone trying to speed things up or simply free some space before a big update. Just something that worked on multiple setups — fingers crossed, it helps yours too!
