You'll need Windowblinds to do that, Tanauser. The skins won't apply without that program.
You can find out more about it here: https://www.stardock.com/products/windowblinds/
There's also a suite of skinning applications available (Object Desktop) here: https://www.stardock.com/products/odnt/
For the free 30 day trial of Windowblinds you won't need Impulse. However, if you decide to go with The subscription products, you will, and you'll mneed to uninstall the trial Windowblinds first.
There are other Stardock products as well to look at here: https://www.stardock.com/products/
And I encourage you to do the research about the products and ask your questions before purchase, although there is a return policy also.
