Okay, my computer was running really slow so I decided it was finally time to do something about it. I went through my Add/Remove Programs list and pretty much deleted every single thing there was to delete. I know, I'm an idiot. The problem is that I deleted everything Windows had on there (for example Windows Installer) and now I'm at the point where my speakers won't even work and I'm really not sure why. It says they are not in installed, and I'm guessing my computer wont let me install it because I deleted Windows Installer. So pretty much my internet and everything runs super fast now, but without sound. What the heck do I do?
