Khmer UI was first introduced in Windows Vista and has served since then as the default Khmer fonts for the Windows User Interface.
Due to the its difficult legibility, the team behind Khmer Unicode (NiDA) introduced Khmer fonts fixer for Windows Vista and Windows 7 (which should also work for Windows 8) in order to replace Khmer UI fonts with Khmer OS Sytem font.
However, in Windows 8, this method doesn't work anymore most likely due to Microsoft's deeper integration of system fonts. In fact, Microsoft has used another font which is actually a combination of three typefaces: Thai, Lao and Khmer. The result font file is called Leelawadee UI (which can be found in the Fonts folder in Windows).
