Project window in VBA has all these unknown sheets

[ammartino44]

Hello. I have all of these projects in the project window and I'd like to delete all of them except the open workbook. I have no idea what these are and when I try to modify it asks for a password.
Solver(SOLVER.XLAM), VBAProject(FUNCRES.XLAM), VBAProject(HsTbar.xla)

These are needed to operate Excel. Do not attempt to remove them or you may corrupt your copy of excel.

Those are all add-ins: File > Options > Add-Ins, Manage: Excel Add-Ins, Go

Uninstall what you don't need.
