There are one of a few places that it could be found, depending on the method used, which can include the system event viewer.
So it would be under control panel? Where at?
Sorry for the delay…. Click Start, then right click "Computer" then click "Manage" as I recall... System Event Viewer is located in there. There are 4 or 5 main categories as I recall. If you take a look at the journaling information on the partition (if it's NTFS, which it should be), you may be able to determine when these files were deleted as well. This may narrow down the time frame you'll need to search through in the system event viewer. Looking at this information however can be rather complicated and often requires an administrative utility such as the Ultimate Boot CD in which to extract this information. So…. There is a way to do this, and yes, it can be done, however doing so is easier said than done. Doing a walk-through of this process would be very difficult to do through a forum based method.
EDIT: After making this post, I just noticed that it appears that you are on Windows 8.1, which by default, does not include the "traditional" start menu. I'm not sure exactly what the back-door method is for Windows 8 & 8.1 to get to the system event viewer since Microsoft bastardized their user interface configuration. That being said though, you can turn Windows 8.1 into a more Windows 7 looking (and working) experience (or to an even older style). If I recall correctly, it's not free, however it's not expensive either. It's called Start Is Back. If memory serves me correctly, it's a one-time charge of $2.99 USD.
EDIT: I also forgot to mention that from my experience, Start Is Back is very different than the free alternatives in that the installer if downloaded through the link I posted here does not come with any added crapware that you likely do not want to opt-into. This is because the program makers use the minimal fee to make their money, instead of pushing the crapware down your throat that they get paid to try to sucker you into installing (and get paid for every time someone does).
