First, let me apologize for my ignorance, I didn't know anything about WindChill until 2 days ago. So my company installed a WindChill 10.1 instance in 2013-2014. It sat mostly idle until about a week ago when they decided they needed it for a project. I'm trying to figure out what are the required security patches for WindChill 10.1. Our security department requires that all current "critical" and "high priority" patches be applied before the application is available for use. I don't want to upgrade WindChill to version 11.1 because another team is working on that project right now. Any help would be appreciated.
Patching Windchill is nothing like patching Windows. This is not something you want to tackle unless you are very familiar with Windchill system administration. Based on your stated lack of experience, I would suggest finding someone else to do this for you.
