New Registry Path with Long Name

Question

Hi All I am trying to add a new registry key which contains a very long value. I can create the registry key :

New-Item "HKLM:SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\Test1.com"

I am trying to add the following value but struggling with syntax - can anyone please help !!!
NOTE - the key is from GPO policy for AppLocker. I found it applied to a domain joined PC and want to use this same value to update the registry for machines that are off the domain.

New-ItemProperty "HKLM:SOFTWARE\Policies\Microsoft\Windows\SrpV2\Exe\11759873-1713-4c87-b95b-925c887337a5" -Name "value" -Value "<FilePublisherRule Id="11759873-1713-4c87-b95b-925c887337a5" Name="MICROSOFT DYNAMICS 365 COMMERCE, from O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US" Description="" UserOrGroupSid="S-1-1-0" Action="Allow"><Conditions><FilePublisherCondition PublisherName="O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US" ProductName="MICROSOFT DYNAMICS 365 COMMERCE" BinaryName=""><BinaryVersionRange LowSection="" HighSection="*"/></FilePublisherCondition></Conditions></FilePublisherRule>" -PropertyType "String"

Hello @Toror72 ,

As @Rich Matheisen mentioned , you would require to use single quotes with the string .

New-ItemProperty "HKLM:\SOFTWARE\Policies\Microsoft\Windows\SrpV2\Exe\11759873-1713-4c87-b95b-925c887337a5" -Name "Value" -Value '<FilePublisherRule Id="11759873-1713-4c87-b95b-925c887337a5" Name="MICROSOFT DYNAMICS 365 COMMERCE, from O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US" Description="R" UserOrGroupSid="S-1-1-0" Action="Allow"><Conditions><FilePublisherCondition PublisherName="O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US" ProductName="MICROSOFT DYNAMICS 365 COMMERCE" BinaryName=""><BinaryVersionRange LowSection="" HighSection="*"/></FilePublisherCondition></Conditions></FilePublisherRule>' -PropertyType "String"  

The above works perfectly as you can see it in the output. The reg.exe does not take large values with spaces in the middle as such and hence gives Invalid syntax .

Hope this output helps. If the information is helpful , please do accept post from @Rich Matheisen as answer so that it helps other members of the community facing similar issue .

Thank you.

You don't say what problem it is that you're having, but I suspect that it's the string literal you're trying to supply in the "-value" parameter.

That string contains double quotes and you're trying to surround the string with double quotes. Try changing the beginning and ending double quotes to single quotes.
