Instructions to apply your new Windows Aero Hybrid Theme
1.) Download all parts(Themepack, Inactive Title Bar accent color registry file, any additional wallpapers, and go to any provided links for extras, such as cursors).
2.) Once files are downloaded, right click each file, open Properties, and unblock them(a small checkbox on the bottom right corner of the General tab)
3.) Zipped files need to be extracted by right clicking and choosing Extract(to any place you wish, I have created a Themes Library folder for this myself, but to Documents, or Desktop is ok too).
You can now delete the Zip files and/or themepack if you wish, once they are applied. Although... I recommend, if you like the theme, save the zipped files somewhere other than the system(C: drive(backup).
4.) Then you just click the Themepack & any additional registry files to apply them. Also place any additional wallpapers in your Pictures library, and add them to the theme or apply as Lock Screen.
Note: To uninstall the theme: just go to Control Panel\All Control Panel Items\Personalization change to another theme, then right click the one you don't wish to have any more, and delete it.
