touch

[orbs]

Linux touch is a very useful shell command to set the "modified" timestamp of a file to current time, as well as create a new empty file if it doesn't already exists. this is for Windows, plus the ability to touch a file from the context menu. also, this single script features a demonstration of an installation process, which includes:

    - unregister pending removal (see Note #1 below)
    - register for all files
    - create registry uninstall entry

also, an uninstall process:

    - unregister for all files
    - delete registry uninstall entry    
    - register pending removal

so you can use it from the command-line, or run as administrator to install, or uninstall from Windows Control Panel.

Note #1: the pending removal is using the "PendingFileRenameOperations" registry value to remove the file next time Windows starts; hence, if you perform an install after an uninstall, the install needs to cancel the pending removal set by the former uninstall process.

Note #2: this is set to run and compile for 64-bit. 32-bit compatibility is left as an exercise for the reader.
