How to uninstall Lenovo HD audio manager, and install just regular Realtek HD audio manager?

Hi, I have a Lenovo Think Centre Edge 72 PC. The PC came with Lenovo variation of Realtek HD audio manager. The problem is that the Lenovo software really lacks some features such as detecting jack, using the rear blue jack for headphones, and so on. The only option I have in "advanced settings" is "Disable front panel detection", and that really isn't enough. When I uninstall it via control panel, and download Realtek HD audio manager from Realtek official web page (Windows 8, 64 bit), it automatically installs Lenovo manager again. I just can't get rid of it. Thanks in advance.How to uninstall Lenovo HD audio manager, and install just regular Realtek HD audio manager

How to Get These Files Back?

I'm on my computer (a Windows 8 Lenovo touchscreen, if that helps) and I thought that "Moving And Replacing" files of the same name would keep both files but, apparently I just lost half of my pictures and they're gone now. Does anyone know how to get my pictures back?
