Aktivasi Windows 8 Release Preview Build 8400 12: How to Enable Aero Effects and Extend the Timebomb

Windows 8 Release Preview Build 8400 12 is the official pre-release version of Windows 8 that was released to the public on 31 May 2012. It features a new Start screen, a redesigned user interface, and various improvements and enhancements. However, some users may want to activate some features that are not enabled by default, such as the Aero transparency effects and the timebomb expiration date. In this article, we will show you how to do that.

How to Enable Aero Effects

Windows 8 Release Preview Build 8400 12 does not have the full Aero Glass theme that was present in previous versions of Windows. Instead, it has a simplified visual style called Windows Basic (Aero Lite) that does not have any transparency effects. However, there is a bug in the Personalization Control Panel that allows you to enable transparency effects for the Windows Basic theme. Here are the steps to do so:

1. Right-click the desktop and open up Personalization, then click on the “Window Color” link given at the bottom of the window. Keep the window open.
2. Open a separate personalization window and apply the Windows Basic theme.
3. Switch to the other personalization window that was opened at the start, uncheck and re-check the “Enable transparency” option and then click on the “Save changes” button. This will cause transparency effects to take effect.

You can also adjust the color intensity and hue of the transparency effects using the sliders in the Window Color window. Note that this bug does not persist if you re-select the theme created, so you will have to repeat these steps every time you want to enable transparency effects.

How to Extend the Timebomb

Windows 8 Release Preview Build 8400 12 has a timebomb that expires on 15 January 2013, after which it will stop working and display a message asking you to upgrade to a newer version of Windows. However, unlike other Windows 8 builds, it contains a broken timebomb that can be bypassed by changing the system date. Here are the steps to do so:

1. Open the Control Panel and click on “Date and Time”.
2. Click on “Change date and time” and set the date to any date before 15 January 2013.
3. Click on “OK” and restart your computer.

This will allow you to use Windows 8 Release Preview Build 8400 12 beyond its expiration date. However, note that changing the system date may cause some issues with other applications and services that rely on accurate time information.

Conclusion

Windows 8 Release Preview Build 8400 12 is an interesting preview of what Windows 8 has to offer, but it also has some limitations and drawbacks. By following the steps above, you can activate some features that are not enabled by default, such as the Aero transparency effects and the timebomb expiration date. However, these are not official or supported methods, so use them at your own risk. If you want to enjoy the full features and functionality of Windows 8, you should upgrade to a newer version of Windows or install a modded version of Windows such as Windows “Project 8400” by ImSwordKing[^1^], which is based on Windows 8 Professional Build 9200 escrow x64 English with all updates installed until November 2021 and includes all sounds, themes and icons from build 8400[^1^].
