2. 

   
   
   Enter a location. A new window will appear asking you to locate the shortcut you just created. You need to determine whether your current Windows version is 32-bit or 64-bit. Copy and paste one of the following (depending on your Windows version) and click on Next:
   • 32-bit:% windir% system32 rundll32.exe advapi32.dll, ProcessIdleTasks
   • 64-bit:% windir% SysWOW64 rundll32.exe advapi32.dll, ProcessIdleTasks

   Name the shortcut. After clicking the Next button, you will see a window asking for a name of the shortcut, you can name it whatever you want.
   • Once done, click Finish.

Part 3 of 4: Clear thumbnail cache with Disk Cleanup

   Select Thumbnails. After scanning, a new window will appear with a list of files that can be deleted. You will see the name and file size in this directory.
   • Find the Thumbnails category and check the box.

   Clear the cache. After ticking the file you want to delete, including the thumbnail cache, confirm the process in the next step by clicking OK and then selecting 'Delete Files'.
   • Congratulations, you have deleted all your unused files, freeing up disk space and improving your computer's performance.
