Uninstall software from script

If your package really does use different productcode GUIDs, then the designers of the MSI package did not design the package correctly. I would verify whether that's really the case before attempting to use scripting to solve anything.

Use this code it will create a Log. If you running windows 7 with UAC make sure you launch the script from a elevated command promt I don't recommend using On Error Resume Next at the top of a script. This disables error handling for the entire script and makes things very difficult to troubleshoot. Each one has a different GUID. Is this the incorrect place to find the GUID?

Is the universal one you're speaking of located elsewhere and I'm just an idiot? Please keep in mind I'm not a sysadmin just a humble helpdesk minion , I had all of this dumped on me this morning after they fired the guy, so yeah, I'm kind of learning as I go here so I totally could be missing something here.

Please, if I've posted in the wrong area, or this otherwise not the correct place to ask this question, please let me know.

I have to query over a thousand computers, and in our testing, this query takes nearly five minutes to complete—that would be three and a half days for only one query.

Hello BT,. Microsoft Scripting Guy, Ed Wilson, is here. I immediately encouraged him to write a guest blog about this issue. The commands and the output from the commands are shown here. The easy way to get this information is to use the Get-WmiObject cmdlet to query for the information. I only need to do this once, and I will have the three pieces of information. A table is a nice way to display the information.

In the code shown here, I use the Get-WmiObject cmdlet gwmi is an alias to return product information, and then I pipe the management objects to the Format-Table ft is an alias cmdlet for display. The following image displays the commands and the output from the commands.

The following image shows massive product reconfiguring going on. The query to return the three parts of the composite key only needs to run once; the values do not change. It is also possible to use the Get-WmiObject cmdlet and a filter to improve the performance of the command a little bit.

This is where quite a bit of experimentation could be required. I have to use the back tick grave character to escape inside quotation marks.

I have to escape the quotation mark and the opening curly bracket for the IdentifyingNumber property. I also have to escape the closing curly bracket and the closing quotation mark. I then have to escape the quotation marks that surround Microsoft Silverlight, in addition to the quotation marks for the Version property.

There are also two quotation marks at the end of the ClassKey.
