If you are still looking for a really good Windows 8 theme for Windows 7 that even adds the Metro App to Windows 7, you can give this UX Theme a try.
Windows 8 UX Theme Includes Themes, Wallpaper, Metro App Desktop, Features
The Windows 8 UX Pack comes with three themes, Windows Aero, Aero Lite and a Metro theme. The Windows 8 UX theme also installs a new logon screen wallpaper, a new desktop wallpaper and adds various Windows 8 features to Windows 7 including a taskbar start Orb, user tiles, the Metro Start UI and the Aero auto-color feature. As you might know, Windows 8 has a cool feature that changes the color of the Aero theme based on the color of your desktop wallpaper
We already have a few apps that add similar features, e.g. Aura Beta adds the Windows 8 auto-color feature to Windows 7, but it is nice to finally have a Windows 8 theme that combines multiple apps, features, themes and even the Windows 8 wallpapers
The Windows 8 theme removes the round corners and adds a user tile to the desktop
Even a skin for the hard drive status:
Metro Desktop And Apps For Windows 7
If you want the fancy Metro desktop with all those cool Metro apps on Windows 7, you definitely need this theme. Take a look:
Known Bugs And Limitation of The Theme (October 2011)
Although this theme works great on many systems it is now flawless. For example I Ran into the problem
expstart.exe – Failed to update BITMAP 6801: 24
After confirming this error message three times, the actual theme should be applied. It looks like the Bitmaps of the Start orbs were not updated, because if I remember correctly 6801 is one of the Start orb BMP’s.
The Windows 8 UX theme tries to establish a connection to 22.214.171.124 via newgen.exe (%PROGRAMFILES%\UX Pack\Newgen\Newgen.exe) – however that is only a connection to Microsoft and the application is generally rated as safe.
Also, the Windows 8 UX theme does not seem to work properly on dual and triple monitor setups and moves the Metro Start bar to other monitors or does not respond.
All in all, I’d say that this is one of the best Windows 8 themes so far and gives Windows 7 an authentic Windows 8 look and adds many of the coolest features. Top!
