Desktop themes have been around since Windows 7 – they usually include things like wallpapers, sound schemes, icons, screensavers and even entire colour schemes for your machine.
You can grab themes you like from the Windows store, or you can customise one and make your own. Whichever you prefer, you can easily find the ones you have at the moment by going to the folder where they are stored.
To find that folder, follow one of the following two methods.
Press the Windows key and R at the same time in order to open the Run command box. Paste the following text into it: %localappdata%\Microsoft\Windows\Themes Press Enter. The folder you are looking for will open automatically.
Use the Search
In order to do this, press the Windows key, then use Ctrl + V in order to paste the same text (%localappdata%\Microsoft\Windows\Themes) into the search function there. Press Enter or click on the Folder that appears at the top of the search results in order to open the Themes folder.
