Patio is correct. I actually uninstalled two programs consecutively. One was Epson printer software, the other one I do not know. After a system restore to a time before the 2 uninstallations, Epson printer software is not restored. So I suppose system restore only deals with Windows system files. And programs installed after the restore point are still there, like Acronis in my case.
Patio, I only have programs and features in Control Panel and within that there's no add/remove programs. There's only the option to uninstall/change/repair. What else can be done?
