Script to collect Windows system information

As an IT administrator of an organization, you might have numerous reasons to gather various device information about your Windows endpoints. For example, you might need specific info regarding the system for troubleshooting or to check the feasibility of running a software application. There are multiple ways to achieve this:

• Using the System Information tool
• Third-party applications
