Chapter 1 - Computer Maintenance - Junk File Tune Up (Windows 10)

Welcome to the next series of chapters covering computer maintenance. The first chapter will be a guide to help you remove junk files that accumulate when we use our machines. We download cookies, images and other content when we view the web. To make it faster cached content or local content is used before making another call to the server. There are files generated when you use Office or other apps. The OS is generating temp files too. The first step is removing all junk and temp files in certain folders and to remove old OS updates that have been piling up in the background and consuming disk space. These files can make your machine work harder and slower to find the content you need. Everything slows down. Cleaning up the hard drive can keep your machine running at top performance.

Let's clean our machine!

Junk File Tune Up

Open the Control Panel using search

Select View by: Category and select Appearance and Personalization

Select Show hidden files and folders

Click on the View tab and select Show hidden files, folders and drives. Also uncheck Hide protected operating system files (Recommended).

A prompt will appear about protecting the files. Click Yes. Close the folder options window.

Navigate to these paths and delete all of the file contents.

%WINDIR%\Downloaded Program Files\
%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.MSO\
%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Word\
%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\
%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\
%userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\
%userprofile%\AppData\Roaming\Microsoft\Internet Explorer\UserData\Low\
%userprofile%\AppData\Local\Google\Chrome\User Data\Default\Cache\

If a folder is in use, check Do this for all current items and click on the skip button.

Go back to the control panel, select Appearance and Personalization and select Show hidden files and folders. (Restoring the initial steps above) Under the view tab, select Dont show hidden files, folders or drives. Check Hide protected operating system files (Recommended).

Click Apply. Close out the control panel. Right click on the start menu and select Disk Management.

Right click on OS hard drive and select properties.

Select Disk Cleanup on the general tab.

A disk clean up calculation window will appear.

When the calculation is complete a new window will open.

Select Clean up System Files button. A new disk clean up calculation window will appear.

Check all of the files to delete and select ok. Select Delete files when the alert prompt appears.
I don't recommend selecting Compress your OS Drive unless you are low on space.

A new clean up window will appear and the files will be removed. The window will close automattically when completed.

You're ready for the next step!


We have cleaned up our files and the next step was to be to defrag your hard drive but with computers and laptops now using solid state drives, we are going to move on to the next step. We will check hardware, OS and drivers to see why our machine is running slow.

We have covered so far...
