Win10 system disk cleanup option disappears solution

However, recently, the win10 user reported that after opening the disk properties, I found that the disk cleanup button disappeared. What is going on? What should I do?

The reason is because the recycle bin is set to “Do not move the file Go to the recycle bin, delete the file immediately after removing it, so you can't find the disk cleanup button in the disk properties, and reset the recycle bin.
Methods:
1. Right-click the recycle bin icon and select “Properties>;

2. In the properties page, select “Customize Size" Set it up and click OK.
