OK, this IS for Windows 2000 and I am attempting the procedure on a Windows 7 machine. That may be my problem.
http://technet.microsoft.com/en-us/library/ee176535.aspx
##################
strComputer = "PC1"
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colSoftware = objWMIService.ExecQuery _
("SELECT * FROM Win32_Product WHERE Name = 'Java(TM)6 update 33'")
For Each objSoftware in colSoftware
objSoftware.Uninstall()
Next
###########################
But otherwise, even though I specify "PC1" as the computer name and "Java(TM)6 update 33" as the product name (just used what was in Add/Remove programs), nothing happens.
Literally nothing. Software remains installed and there's no error message. Nothing pertinent as far as I can see in Event Viewer.

This script does not work either:
#######################
'Start Script
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
'Uninstall Java(TM) 6 Update *
Set colJava6dot = objWMIService.ExecQuery("Select * from Win32_Product Where Name like 'Java(TM) 6 Update %'")
For Each objSoftware in colJava6dot
objSoftware.Uninstall()
Next
######################
Yes, I trimmed the script shared here, since I only have Java 6 to contend with:

OK, while I still would be interested in knowing why the above-mentioned .vbs scripts do not work, I seem to have attained my objective with a simple .bat script (as usual the .vbs gibberish seems less efficient than a one line .bat - or .ps1).
So... using the GUID found here (the value of the ProductID key):
Computer\HKLM\Software\Microsoft\Windows\CurrentVersion\GroupPolicy\AppMgmt\b837...f01\ProductID
I run the following script as a Startup Script in a GPO:
msiexec /x {GUID_from_location_above} /qn
-------------------------------------------
I *seem* to have a clean uninstall, i.e. references to the GPO removed as described here so a reinstall would be possible (if that's what you're after):

In the first script you've provided from the TechNet page, you changed the value of the strComputer variable from "." to "PC1".
Try using the "." as provided in the example on TechNet, this will use 'localhost' instead of the name you're forcing it to use.
By the way, mostly the easiest solution is the best... I like your solution where you look up the GUID and use msiexec :-D |
Greetsz,
Jeff. |

I tried it both ways, with "PC1" and ".".
For the second script, I left it "." |

Just tested it in Powershell
$a = Get-WmiObject -Query "Select * from Win32_Product Where Name like 'Java(TM) 6 Update %'"
$a[1].Uninstall()
Non Elevated prompt:
I get return code 1603, and nothing happens
Elevated Prompt:
I get return code 0, and it is uninstalled.

No, I did not try it without UAC. Looks like that might have something to do with it.
quote:
$a = Get-WmiObject -Query "Select * from Win32_Product Where Name like 'Java(TM) 6 Update %'"
$a[1].Uninstall()
That is so concise!
And most of it is the WMI query.
$a[1].Uninstall()
So once you establish a value for that variable (is that the correct way to say it?), the "uninstall" method of (of what? WMI-Object?) removes the program.
But why $a[1] rather than just $a ?
Where does the 1 in brackets come from? |

Sorry about the confusion Aval
I assign the result of the WMI query to the variable $a, that will then contain either a single object, or a collection of objects (If the query returns multiple results)
I my case it returned 2 results because I had 2 editions of Java 6 on my machine.
In my case $a then contained a collection of 2 objects. So $a[1] just references the 2nd item in the collection. (First item is $a[0])
So if you wanted to remove all instances you should be able to do something like
$a | Foreach {$_.Uninstall()} |
