There are a couple of ways to get there from here. The simplest (and safest, depending on your comfort level where editing the registry is involved) is to use a batch file and place it in the \Windows folder. For example, your batch file (named "dailybackup.bat" for consistency), might contain the following:
@echo off
pushd
cd /d c:\utils
dailybackup.exe
popd
I use this method for a number of commands/processes that I regularly use at the DOS prompt.
Alternatively, you can create an "alias" for the executable in the registry. To do this, go to "HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths." You'll see a whole lot of sub-keys here. What you want to do is add one for "dailybackup.exe." Right-click on "App Paths" and select "New" and "Key." Enter the key name (ending with .exe). (This is an opportunity to use a shortened version of the name, if you wish, such as "dbu.exe," for example. Anyway, enter your alias (we'll just go with "dailybackup.exe"). Now, in the right-hand pane, double click "(Default)" and enter the full path and name of your executable ("c:\utils\dailybackup.exe"). That's all there is to it. You're done with the registry. To use the new alias, you can hit (Windows Key)/R to get the "Run" box and enter your alias. For reasons which escape me, the alias won't work directly from a DOS prompt, but needs to be prefaced with "start," as in:
C:\Some\Random\Folder >START dailybackup
or, if you opted for a shorter alias:
C:\Some\Random\Folder >START dbu
Hope that helps.
