You can check for updates here and download and install them.
Press Windows key+I to open Settings and click on Updates & Security. I would suggest you update your OS as well while you are at it. Rebooting your Windows 10 computer can solve a lot of common and small errors like the one you are facing right now. Check if the recycle bin icon is grayed out on the desktop now. Unselect the Recycle Bin option here and save everything. Select Themes from the sidebar in the Settings windows that opens next, scroll a little, and click on Desktop icon settings here. Right-click anywhere on the desktop to select Personalization. That will lead to a series of problems like you can't empty the recycle bin, can't access the recycle bin or restore deleted files/folders, and can't access the recycle bin settings because they are also grayed out. That's until you can't access it because Recycle Bin is grayed out in Windows 10 computer. Whether you deleted it accidentally or need to take another look, the recycle bin is there to save the day. The Recycle Bin acts as a failsafe for when you delete a file or folder and need to restore it.
