OK, so I think this answers my question. I'll just stick to x32 until Dell switches all DUPs to x64. No point in a partial update.  [URL]#20311509
Been using Repository Manager for a while and like the tool. I am a little confused regarding the Windows x64 bundles though. If I export a Windows x64 bundle, it only contains a subset of updates contained in the x32 bundle. For example, BIOS is missing entirely. If I want to update my entire system (firmware and drivers) it seems I have to stick with the x32 bundle. What is the purpose of the x64 bundle if it only handles certain components? When would (should) I use the x64 bundle? From a size perspective, the v474 bundle for Windows x64 is about 500MB and the x32 version of the same bundle is 1.45GB!
