It turns out there is an easy setting that forces the resolution to match the window size. Even if you end up with really weird window sizes.

There are two ways (that I’ve found) to turn this on. The easiest is under the menu for the window (left click on the icon at the top left of the window). Then select Smart sizing. (There will be a check to the left of it if it’s turned on.)

On the other hand if you want to make a more global change you can add the /span setting to your shortcut for Remote Desktop.

DOS/CMD

Unlike the original DOS machines you can actually open multiple DOS windows. Technically they are actually CMD windows, just FYI. You can also create multiple Powershell windows.

Here is a list of common DOS/CMD commands. I’ve also got a post here where I go over a bunch of things useful in batch files, some of which you might find useful here too.

Some of my favorites (see the above link for details and more commands):

• cd – change directory
• cls – clear screen
• copy – copy file(s)
• del – delete file(s)
• dir – directory listing
• find – find a string in a file
• help – available commands (<– Important command here folks)
• md (mkdir) – make a folder (directory)
• more – displays a file’s contents (paginated) (space bar to page, enter for a single line)
• move – move a file
• ping – test connection to another host
• rd (rmdir) – remove a folder (directory)
• ren – rename file(s)
• type – displays a file’s contents (no pagination)
• Save output from a DOS command to a file: > (overwrite) or >> (append)
  For example:
  DIR > MyDir.txt
  DIR >> MyDir.txt

Some other handy CMD/PoSH commands

CMD

• List drives: fsutil fsinfo drives
• List drive size and free space: fsutil volume diskfree C:
• List services: sc query
• Show all mounted disks: wmic logicaldisk list brief
• Name of the current server: hostname
• Display environment variables: set

 
PoSH

• List drives: Get-PSDrive
• Show all mounted disks: Get-Volume
• Name of the current server: hostname
• Display environment variables: set
• Show the date/time: Get-Date
• Show installed Features: Get-WindowsFeature
• Add Windows Feature: Add-WindowsFeature
• Run PoSH as an administrator: Start-Process -FilePath “powershell” -Verb runAs
• Show services Get-Service | sort-object
• List drives, sizes and free space (replace server name):

  Get-WMIObject Win32_Logicaldisk -filter "" |
  Select PSComputername,DeviceID,
  @{Name="SizeGB";Expression={$_.Size/1GB -as [int]}},
  @{Name="FreeGB";Expression={[math]::Round($_.Freespace/1GB,2)}}

• Show drive size, letter, volume name, partition:

  Get-WmiObject Win32_DiskDrive | % {
    $disk = $_
    $partitions = "ASSOCIATORS OF " +
                  "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                  "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
    Get-WmiObject -Query $partitions | % {
      $partition = $_
      $drives = "ASSOCIATORS OF " +
                "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
                "WHERE AssocClass = Win32_LogicalDiskToPartition"
      Get-WmiObject -Query $drives | % {
        New-Object -Type PSCustomObject -Property @{
          Disk        = $disk.DeviceID
          DiskSize    = $disk.Size
          DiskModel   = $disk.Model
          Partition   = $partition.Name
          RawSize     = $partition.Size
          DriveLetter = $_.DeviceID
          VolumeName  = $_.VolumeName
          Size        = $_.Size
          FreeSpace   = $_.FreeSpace
        }}}}

Net commands

I don’t know much about the net command but here are some handy uses:

• Dealing with shared folders (really handy if you need to copy files back and forth from another location): (Note: Powershell command included where I know it.)
  • List shares:
    NET SHARE
    Get-SmbShare
  • New share:
    NET SHARE MyShare=E:\ /grant:domain\user,full
    New-SmbShare -Name “MyShare” -Path “E:\” -FullAccess “domain\user”
  • Remove a share:
    NET SHARE MyShare /DELETE
    Remove-SmbShare -Name “MyShare”
• Create, modify or remove Windows users and groups
  • NET USER “NewUser” “NewPassword” /ADD
  • NET USER “NewUser” /DELETE
  • NET LOCALGROUP “NewGroup” /ADD
  • NET LOCALGROUP “NewGroup” /DELETE
  • etc.
• Same command as above but here’s how you view members of the administrators group, or add/remove people from that group.
  • NET LOCALGROUP administrators
    Get-LocalGroupMember -Group administrators
  • NET LOCALGROUP administrators “NewUser” /ADD
    Add-LocalGroupMember -Group Administrators -Member NewUser
  • NET LOCALGROUP administrators “NewUser” /DELETE
    Remove-LocalGroupMember -Group Administrators -Member NewUser

Run Powershell/CMD remotely.

Powershell
If your current id doesn’t have permissions on the remote machine then right click on Powershell and select Run as different user. Otherwise just open Powershell. Run the following code, replacing XXX with the computer name.

Enter-PSsession -computername XXX

CMD
Same instructions as above but with a CMD shell.

winrs -r:XXX cmd

Common tools still available

• Task Manager: tskmgr (or Ctrl-Alt-End and use arrow keys)
• Registry editor: regedit
• Notepad: notepad
• msinfo32: msinfo32
• Windows Explorer: (Sort of) open Notepad or msinfo32 and go to file open.

Help! I’ve closed all of my CMD windows!

You can also hit CTRL-ALT-END (the same as hitting CTRL-ALT-DEL on your local machine) and select Task Manager. Then go to File->Run New Task. Once a prompt comes up type CMD and a new command shell will come up.
 

Logging off

To log off of the machine you have to use the logoff command. You can also hit CTRL-ALT-END and select Sign Out. Do not use exit as it will close the current CMD window and not log you out. If for some reason you close out the window and need to open a new one see above.
