The landlord should have deleted the picture folder in the X:\Windows\Web\Wallpaper directory (X refers to your system drive letter) (if you didn't manually delete it yourself, you probably used the system drive slimming function of some software).

Recovery is simple. Find any win7 computer, find this directory to copy, or put it in this directory.

There is nothing special about the skill of using win7 theme. If the landlord's situation is not the family version first, then you can use the theme.

But if you use a third-party theme (that is, unlike Microsoft's theme of changing colors for wallpaper), you must first crack it. Theme cracking tools can be found on the internet by yourself. The name is UniversalThemePatcher, or the beautification in win7 optimization master also has the function of cracking system patches.

There are many third-party topics on the Internet. As I just said, China's original website has a magic desktop and a theme house.

Some websites are made automatically, but there are also some foreign themes that are not automatically installed.

Generally, after downloading a theme that is not automatically installed, you can extract an aaa.theme file and an aaa folder and put them in the directory X:\Windows\Resources\Themes\.

Double-click aaa.theme again. (aaa refers to any file name. Generally speaking, it doesn't matter whether two names are the same or different. )

I have said it in detail. If the landlord still doesn't understand, please leave a message ~
