Bugs and quirks[edit | edit source]
Timebomb[edit | edit source]
It is one of the notable Windows 8 builds to not activate the timebomb if you install it on the current date.
Transparency effects in the Windows Basic theme[edit | edit source]
When using the Windows Basic visual style, transparency effects can be enabled by means of a bug in the Personalization Control Panel. To do so:
- Right-click the desktop and open up Personalization. Now click on the "Window Color" link given at the bottom of the window. Keep the window open.
- Open a separate personalization window and apply the Windows Basic theme.
- Go back to the other personalization window that you opened at the start, uncheck "Enable transparency" option and then re-check it. Click on "Save changes" button. This will cause "glass" effects.
