Manually Delete Temp Files in Windows 11 for an Instant Speed Boost

If your Windows 11 PC feels sluggish, there’s a quick, safe cleanup trick you can do in just a few minutes: manually deleting temporary files. This simple routine can instantly free anywhere from 1–10GB on a cluttered computer, giving you more space and often a noticeable speed boost, without installing any extra software.

Step 1: Open the Hidden %temp% Folder with Win+R

Start by pressing Windows key + R on your keyboard. This opens the Run dialog, a handy little box that lets you jump straight to system folders. In the text field, type %temp% (including the percent signs) and press Enter. Windows will open a folder packed with temporary files created by apps, installers, and the operating system itself.

Step 2: Select Everything and Delete the Junk

Inside the %temp% folder, press Ctrl + A to select all files and folders. Then press Delete on your keyboard, or right-click and choose Delete. You might see a few warnings saying some files are in use. That’s normal—just click Skip for those. Everything else can safely go to the Recycle Bin. These are temporary leftovers your system no longer needs for everyday use.

Step 3: Repeat for temp and prefetch in the Run Dialog

You’re not done yet—there are two more locations worth cleaning. Press Windows key + R again, but this time just type temp (without the % symbols) and hit Enter. When the folder opens, select everything with Ctrl + A and delete the contents, skipping any files that Windows says are in use.

Repeat the same process one more time: press Windows key + R, type prefetch, and press Enter. If you see a permission prompt, click Continue. Again, press Ctrl + A to select everything and delete. The prefetch folder stores data that helps Windows start programs faster, but it’s completely safe to clear. Windows will automatically recreate fresh prefetch data as you use your apps.

Step 4: Empty the Recycle Bin to Claim the Space

Right now, everything you deleted is still sitting in the Recycle Bin, which means it’s still taking up space. To finish the cleanup, right-click the Recycle Bin icon on your desktop and choose Empty Recycle Bin. Confirm when prompted. Only now is the space truly freed, and on a cluttered PC, that can easily be 1–10GB or more.

Is It Really Safe to Delete These Files?

Yes, these files are safe to delete. They are designed to be temporary. Windows and your apps recreate any needed temp or prefetch files automatically the next time you use them. At worst, a program might take a fraction longer to start once while it rebuilds its cache—but you gain back valuable storage and often smoother overall performance.

Make It a Simple Monthly Habit

For the best results, turn this into a quick monthly routine. Set a calendar reminder and run through the steps: Win+R with %temp%, then temp, then prefetch, and finally empty the Recycle Bin. It only takes a few minutes, keeps your Windows 11 system feeling fresh, and helps avoid slowdowns caused by years of digital “dust” piling up in the background.
