Acronis TrueImage Home saves its backup jobs in script files, located in %ProgramData%\Acronis\TrueImageHome\Scripts.
Each backup job has to be set up manually, once.

Run a backup job:

    TrueImageLauncher.exe /script:"script_name_without_path_and_without_any_extension"

For example, running a DIR command against my Acronis backup scripts folder reveals the following files:

 Volume in drive C is WINDISK
 Volume Serial Number is C0FF-EE01

 Directory of C:\ProgramData\Acronis\TrueImageHome\Scripts

21-03-2016  14:12    <DIR>          .

    iexplore.exe -private [ url ]

Open Internet Explorer in Windows Explorer mode (IE 7 and earlier versions only):

    iexplore.exe -e Folder

It is not possible to start a Windows Explorer window with alternate credentials.
That is where Internet Explorer's "Explorer mode" comes to the rescue:
use RUNAS and IE's -E switch to start an Explorer look-alike window with alternate credentials.
Folder can be in "drive:\path" or UNC format.

As of IE 7 this workaround may no longer work, as the -e switch became obsolete (though it still does work on my Windows 7 (64-bits) system).
You may want to try this "direct" approach first:

    explorer.exe /separate[,Folder]

This works in Windows 7 (64-bits), not sure about other Windows versions though.

Create a multi-page PDF from all JPEG files in the current directory and save it as MULTIPGAGE.PDF in the same directory:

The last example uses the /one switch to allow only one single instance of IrfanView.
If this switch is omitted, multiple instances of IrfanView may be trying to write to the file simultaneously, resulting in "in use" errors.
Wait until IrfanView is no longer running in memory before trying to open the PDF file (this may take several minutes, depending on the amount of data to be processes).

Note	1:	All switches must be in lower case.

Reflect.exe uses an XML file for its backup job parameters (source disks/partitions, target folder, etcetera).
The XML file must be created by a (manual) setup, and will be saved as "My Documents\Refect\My Backup.xml" by default.
Once the XML has been created, it can be used to run Reflect from the command line or a script.
It is possible to create multiple XML files for different backup jobs.

Run a full backup:

    reflect.exe -e -full "%UserProfile%\Documents\Reflect\My Backup.xml"

Run an differential backup, wait if reflect.exe is still busy:

    reflect.exe -e -diff -w "%UserProfile%\Documents\Reflect\My Backup.xml"

Macrium Reflect backups can be verified from the command line with mrverify.exe, which must be downloaded separately.

List all available CD/DVD writers with their ID number and drive letter:

Create and burn a new ISO file to the CD/DVD writer with ID number 2:

    miso.exe ISOFileName.iso -c NewFolder -f NewFolder -a *.* -l3 -l VolumeLabel -be 2

Notes:	The -c switch creates a folder NewFolder in the root directory of the ISO image, the -f switch makes this new folder the working directory.
	-a *.* adds all files from the current directory, including subdirectories, to the ISO image's working directory.
	-be 2 tells the program to quick erase the disk in the CD/DVD writer with ID number 2 if it isn't blank, and then burn the ISO image to the disk.
	If ISOFileName.iso already existed, the files and folder(s) will be added to the existing ISO image.
	Use -l1 instead of -l3 if you want to restrict file and folder names in the ISO image to their short "8.3 notation".

Delete files from an existing ISO image:

Print a Word document:

Open Word and create a macro file with the following content (tested in Word 2007 English, you may need to tweak the code for other versions or languages):

Sub PrintDefault()
'
' PrintDefault Macro
' Print current document to Default Printer
'
	ActiveDocument.PrintOut
	ActiveDocument.Close
	Application.Quit
End Sub

Save the macro as "PrintDefault" in normal.dot. You only need to do this once.

Or download it here, and unzip and import it to normal.dot:

From now on, you can print a Word document using the following command:

	winword.exe WordDocument /mPrintDefault /q /n

This command opens WordDocument in Word, prints the document, closes it and exits Word.
The /q switch suppresses the "splash screen", the /n switch opens a new instance of Word, so WordDocument won't show up in the list of documents in any other open instance.
Unfortunately, I haven't found a way yet to hide Word from view during the process.

Notes:

It is possible to create a macro that prints to an alternative printer instead of the default. Save this macro giving it a logical name, and use that macro in the command to print to that alternative printer. Using macro's on the command line opens up other possibilities too, like saving a file in a different format. Have a go at it!

Notes:

It is possible to create a macro that prints to an alternative printer instead of the default. Save this macro giving it a logical name, and use that macro in the command to print to that alternative printer. Using macro's on the command line opens up other possibilities too, like saving a file in a different format, or converting ("publishing") it to PDF... Have a go at it!
