Delete that bad boy, could be a collection of personal info you may not want looked at from the net...
If you dont know what it is, I doubt youll miss it..
If the location is unknown and you've launched WinDirStat as administrator, the file may reside in shadow copies. Start the command prompt as administrator:
If the size of shadow copies is significant enough, press Win+Pause - System Protection - select drive C - Configure - Delete all restore points.Code:vssadmin list shadowstorage
Otherwise, make sure you start WinDirStat as administrator, because if it can't access a folder, it can't take it into account.

Try another tool, like treesizefree and see what it says about the file.
Yes, you can delete the regtrans files. Not the Hives, obviously.
Probably easiest to use a .cmd for that.
