Is it possible to disable indexing already in the ramdisk configuration?
As by default, the Windows search index is enabled even on the ramdisk.
Admittedly, you can restrict the windows search index to certain folders or even disable it completely. So maybe the ramdisk would not be indexed, although the ramdisk properties show otherwise.
However maybe it is still easier for some people to choose "index enabled / disabled" in the ramdisk configuration utility than to play with services.msc.
