I am trying to find a way to change the value of a registry key on a lot of computers. The key i want to change is basically the 'Computer Description' which is located in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\LanmanServer\Parameters\srvcomment
. Anyone know how this is possible with powershell or even any other way this can be done remotly.
 Thanks in advance

1. Export your registry key
2. This will give something like this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\LanmanServer\Parameters]
"ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,\
  00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,\
  73,00,72,00,76,00,73,00,76,00,63,00,2e,00,64,00,6c,00,6c,00,00,00
"ServiceDllUnloadOnStop"=dword:00000001
"NullSessionPipes"=hex(7):6e,00,65,00,74,00,6c,00,6f,00,67,00,6f,00,6e,00,00,\
  00,6c,00,73,00,61,00,72,00,70,00,63,00,00,00,73,00,61,00,6d,00,72,00,00,00,\
  62,00,72,00,6f,00,77,00,73,00,65,00,72,00,00,00,00,00
"autodisconnect"=dword:0000000f
"enableforcedlogoff"=dword:00000001
"enablesecuritysignature"=dword:00000000
"requiresecuritysignature"=dword:00000000
"restrictnullsessaccess"=dword:00000001
"Lmannounce"=dword:00000000
"Size"=dword:00000001
"AdjustedNullSessionPipes"=dword:00000002
"Guid"=hex:cd,d5,3d,19,02,3a,98,4c,bb,0f,97,01,f4,47,07,49
"srvcomment"="Description changed by script"

3. Delete all irrelevant value lines
4. copy the *.reg file to each workstation
5. Double click the file or execute it by script.

Or use the information on this page:

You have Windows Batch scripting as on of yoru zones, asuming a batch file is an acceptable method then you can easily edit a remote computer's registry file however you like assuming that you have administrator credentials to that machine as follows:

REG ADD "\\ComputerName\HKLM\SYSTEM\ControlSet001\Services\LanmanServer\Parameters" v/ srvcomment /t REG_SZ /d "This will be the new Description of the Computer!" /f

For a bit more likely usage in a script see attached.
SET "Cmp=RemoteComputerName"
SET "Key=HKLM\SYSTEM\ControlSet001\Services\LanmanServer\Parameters
SET "Item=srvcomment"
SET "Data=This will be the new Description of the COmputer!"

REG ADD "\\%cmp%\%Key%" /v %Item% /t REG_SZ /d "%Data%" /f

Open in new window
