Accidentally deleted a bunch of files from appdata/local, what do I do now?

So, I had a program acting up, so just to check if it was something in the appdata/local folder, I tried deleting the files from there, halfway through my automatic response to seeing stuff in recycle bin was to empty it, I did and realised what I did, I hit cancel but it didn’t work, I fucked up big time. Now UAC isn’t working, no matter what you click (yes or no) it doesn’t work, and I’m not sure what else will be going wrong. I can’t run any recovery programs because of that and they won’t keep the folder structure.

Is there anything I can do or did I just fuck up this install and I need to do a whole reinstall to fix this? sigh
