If you are new to Windows 8 and want to use the Aero themes on it, here’s how on the Consumer Preview.
Aero themes offers a glassy touch and feel of Windows with nice settings of programs. However, such an option is not really enabled in Windows 8 Consumer preview version if you want to enjoy it. As a result, you would have to manually activate it by making some tweaks.
You have to make changes in the registry, and it is my word of advice NOT to proceed ahead if you do not understand the steps given below. Better have an experienced person supervise you in following the process:
1. Logon using windows 8 admin account
2. Press the Windows Hot Key + R simultaneously to initiate Run. Type in REGEDIT and enter the windows registry of the system.
3. On the left hand side you need to go to the following directory HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM. Now go to the right pane and right click on the white background to create a new DWORD (320bit) value as shown below.
3. Rename the newly created DWORD (32-bit) Value to UseMachineCheck. Press enter to make sure its value is set to 0. In the similar manner create Animation, and Blur with their values set at 0 too as shown below
4.You are done. Just exit the Windows Registry and restart your system so that the changes you made are in effect. Right click on the Desktop and click Personalize to apply the Aero theme option.
