I'm trying to edit a particular section inside the Local Security Policy snap in and I'm wondering if I really need to give all of these groups (I think they're groups) permissions. Based on this information I may remove the same groups from other parts of the snap in but these look strange particularly the number ones and possibly Classic .NET AppPool. I do development in Visual Studios but I don't do development in ASP.NET or at least haven't in a number of years. I'm wondering if it's safe to remove them without causing future headaches. It may be that the only way to know for sure is to remove them and then do things that I normally do to see if they work properly but maybe someone else has already been through this experience. Here's a screenshot of the particular section I'm looking at but the same user groups will be in other places to remove.
