How do you create system variables via batch file for Windows 7?

Question

How can I create a batch file which creates a new system variable?

(You know, in advanced system settings > environment variables > System Variables).

I want to create a new variable named FLEXLM_TIMEOUT and set its value to 10000000.

I need to figure out a way to create this variable in an automated fashion as I have around one hundred computers that need this fix.

Solution

You are looking for the SetX command:

 setx FLEXLM_TIMEOUT "10000000" /m

Should do what you are wanting.

This command has been standard in Windows since Vista and XP had it available in the XP Support Tools. It also has the ability to set variables on remote machines if needed.

Corporate IT issues are off topic.

@CharlieRB This is a question about usage of Windows which is on-topic.

@KevinPanko Sorry. I see it differently. The help center specifically states "issues specific to corporate IT support and networks" are off topic. If the question didn't state "I have around 100 computers that need this fix", I'd probably agree with you.
