I don't know if it's still the same but when I used to install Service Packs, you had the option to enable or disable the removal feature.
I don't recall the default.
If you don't know which option you took, I would start an install on a 3rd machine and see.
Hope this helps.

Subject: iSeries Access service pack SI50567
Has anyone else had issues with this service pack? I just installed it on my second Windows 8.1 machine and it has a weird problem where the emulator screen disappears until the next input.
Not sure of a workaround - is there a way to uninstall a service pack?
