C:\Windows\winhlp32.exe
installed with Windows 8 is a stub only (~10KB). It does not shows or open .hlp
files! You have no need to erase this file.
There is optional update KB917607 (.msu) for Windows 8 which allows to work with .hlp
files, but this update may be installed manually by the user only. After installing this update C:\Windows\winhlp32.exe
will be more than 100KB (can't say exactly).
