How to Clean Junk Files and Cache on Windows 10 C Drive in 2022 – Cleaning junk files and cache in Windows 10 regularly is very useful to speed up slow Windows 10 and keep C: drive (system partition) from getting full quickly. Junk files and cache if too many can make our computers very slow.
Old cache files are usually not needed anymore. But by default, this file will still be stored on the hard disk.
Every time we run applications such as browsers, these junk files will keep getting bigger, so we need to clean them regularly so that they don’t fill the hard disk and burden the system.
In addition, every time you finish updating Windows 10, it will also leave a fairly large cache file on the hard disk, usually above 5 GB.
Well, usually this file makes the C: drive full quickly. The solution is to delete it, so we can get free space for other applications.

How to clean junk files in Windows 10
1. Clean drive C automatically using the Storage sense feature
Storage sense is one of the coolest Windows 10 features to clean cache files and other junk files on drive C.
If we enable this feature, the system will automatically perform periodic cleaning according to the time we set.
Because this feature is a built-in feature, so we no longer need to install additional applications to clean our C drive.
- Go to storage settings by typing storage in the windows search bar, then select storage.
- Go directly to the Storage sense section then activate it by clicking the button until it says on. Then go to the Change how we free up space automatically menu .
From here we can set when the cleaning of the C drive will automatically be carried out, whether every day, every week or every month.
We can also set the system to automatically delete temporary files after 1, 14, 30, or 60 days.
In the Storage sense section, you can set it to run every week, so that the junk files on drive C are cleaned regularly every week.
Check the Delete temporary files option and set the time to 30 days. This feature functions to delete temporary files that can make the hard disk full and burden the system.
Set Never in the Delete files in my Downloads folder, because this feature is used to delete all files in the Downloads folder.
2. Clear Windows Update cache files
Every time you update, Windows 10 will store a cache file of a size large enough. If we have a small C partition, these files can make the hard disk full quickly, especially Windows 10 often updates several times a month.
Therefore clearing Windows update cache files will be very helpful to free up more space on drive C.
Go to Storage settings , in the Storage sense section, click on the Free up space now option .
Wait until the scanning process is complete, it usually takes a few minutes depending on the size of the C drive and the number of junk files that exist.
After scanning is complete, click Remove files .
Make sure the Windows Update Clean-up section is checked. Friends, you can see in the example above, the cache size of the windows update on my computer reaches 3.26 GB, still relatively small because usually, it can be up to 5-6 GB.
By cleaning this cache file, our C drive will remain clean of junk files and not full quickly.
3. Clean cache files on drive C with the Total PC Cleaner application
We can also clean junk files in Windows 10 by using the help of tools from the Microsoft Store. One of the best cleaner apps for Windows 10 is Total PC Cleaner.
This application works well enough to detect various types of leftover files that are no longer needed, and we can clean them to keep the hard disk from filling up quickly.

4. Clean junk files in the system registry with the CCleaner application
Cleaning junk files in the system registry can also be useful for maintaining the performance of our Windows 10 system. We can use the CCleaner application to do it automatically.
Junk files in the system registry don’t take up too much space on drive C, but they have more of an effect on performance.
If we have a laptop with mediocre minimum specifications, the registry junk files that accumulate can make it slow.
5. Clean residual program files that have been deleted with Revo Uninstaller
When we delete a program sometimes not all files from the program are deleted. There are still residual files that are still stored on our C drive, these files are often also referred to as leftover files.

We also uninstall programs via Revo Uninstaller, so that there are no leftover files left when removing a program.
