Win10 default is white as a system application background, white is not bad, it is normal. However, some people want to taste the dark subject, a more personal theme. Today, based on my experience, I tell everyone how to open the Diablo theme.
Open the Registry Editor. In the bottom left corner of Win10 there is a search bar, enter Regedit inside, press enter, there will be asked permission interface, click [is] as shown.
Change the key # 1. Navigate to KEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Themes \ Personalize by double-clicking each folder or by clicking the drop-down button in the folder. As shown
If you can not find the subitem Personalize, we can create one such subkey. If you find such a sub-item, look directly at step 5.
Create a sub-item Personalize. If you do not find the sub-item Personalize, right-click the Themes folder, select "New", then select "Item" and name it "Personalize". As shown
Create a new double byte Right-click on the Personalize folder, select New, select DWORD (32-bit) and name the double-byte AppsUseLightTheme. As shown
Correct the key. In the AppsUseLightTheme folder, right-click, select "Modify", if the key is 0, do not control, otherwise, to 0. As shown
Change the key # 2. Repeat the above steps, but this navigation path to HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Themes \ Personalize. Once again, create a new double-byte (32-bit) key for AppsUseLightTheme, assigned a value of 0.
Finally log out Win10, and re-login. [Start Menu], and then click [your avatar], select [logout], Diablo theme set so successful haha. I hope for your help, thank you for reading. As shown
