Hello mwu, and welcome to Eight Forums.
Was this a result of your computer being infected by a virus or malware, or done by mistake?
If you are not sure that I would recommend to do a full scan your system at boot with Windows Defender Offline to help make sure it's clean.
You might see if you may be able to right click on the .reg file, click on Open with, and click on Registry Editor if listed. If not listed, then click on Choose default program instead, and browse to and select the C:\Windows\regedit.exe file.
Afterwards, you'll hopefully be able to merge the needed .reg files. I would say you need at least the .exe and .lnk (LNK) ones.
If you are still unable to merge them, then you might see if doing a system restore at boot using a restore point dated before you had this issue may be able to undo and fix this.
Hope this helps for now, :)
