To know which is the username associated with a known SID (Security Identifier), open the registry (regedit.exe) at this location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.

Each SID key has a ProfileImagePath string whose value is the user path which contains the username.
To know which is the SID associated with a known username, select the ProfileList key and search the username.

There is also a SysInternals command-line utility which shows the SID associated with a known username:

How to mount an image file and access image content

To get access to the content of a virtual machine image or a ISO file, follow these steps:

• associate the file with a loop device node:
  # losetup /dev/loop0 /var/otheros.img
• list the partition table of the device:
  

  # fdisk -l /dev/loop0 
  Disk /dev/loop0: 21.4 GB, 21474837504 bytes 
  255 heads, 63 sectors/track, 2610 cylinders 
  Units = cylinders of 16065 * 512 = 8225280 bytes 
        Device Boot      Start         End      Blocks   Id  System 
  /dev/loop0p1   *           1        2609    20956761    7  HPFS/NTFS

• create device map (kpartx is part of multipath-tools package on Ubuntu):
  

  # kpartx -a /dev/loop0
  # ls -l /dev/mapper/ 
  total 0 
  crw-rw---- 1 root root  10, 62 Jul  6  2008 control
  brw-rw---- 1 root disk 253,  0 Jul  5 23:18 loop0p1 

• mount the device partition:
  # mount /dev/mapper/loop0p1 /mnt

Launching control panel dialogs from command line

It is possible to directly open the control panel configuration dialogs writing commands in the Run dialog or in a dos prompt window:


control admintools: open Administrative Tools
control date/time: open the Date and Time properties
control desktop: open the Display properties
control color: open the Display properties and go to Appearance tab
control folders: open Folder Options
control fonts: open the Fonts properties
control infrared: open the Infrared properties
control keyboard: open the Keyboard properties
control mouse: open the Mouse properties
control netconnections: open Network Connections
control telephony: open Phone and Modem Options
control printers: open the Printers properties
control international: open the Regional Settings
control schedtasks: open the Scheduled tasks
control userpasswords: open the User Accounts properties
control userpasswords2: open the Advanced User Accounts properties
control: open the control panel

If the "Safely Remove Hardware" icon disappears, the control command can help:
control hotplug.dll: open the "Safely Remove Hardware" window

Every *.cpl file in the Windows directory can be opened with the control cplfile command:
control vp7dec_settings.cpl: open the On2 VP7 Decompressor Settings, if VP7 codec is installed.

Moreover, some cpl files accept two arguments:
control cplfile[,[@first][,second]]: the first argument indicates the function (if a cpl file controls multiple functions), the second argument indicates the tab of the window to display.
control main.cpl,@0,2: show the 3rd tab of the mouse properties (main.cpl controls mouse and keyboard, @0 is for mouse properties, 2 is the 3rd tab)
control main.cpl,@1,0: show the 1st tab of the keyboard properties (@1 is for kbd properties, 0 is the 1st tab)
