, the file which cannot be deleted is an exe file which installs the video card drivers and was downloaded directly from the NVIDIA website. I've downloaded many of these files, while in Win 7, and never had any problems deleting it once the drivers were installed. Since I've upgraded to Win 10 now I'm getting this problem. I use REVO UNINSTALLER when deleting programs cause it does such a good job of rooting out all the extraneous stuff which is usually left behind by the program uninstaller. Normally you shouldn't have to use REVO when updating video drivers as they are normally overwritten by the new install. I've checked where the program files are being used by using REVO and AUTORUNS (Microsoft put this out years ago) and all are being used from Program Files (X86) and also checked Task Manager and none are being run from the Dowloads folder. Seems to me that Win 10 is treating this file as if it were part of the operating system, or parts thereof. In Win 7 I would normally go into safe mode and delete the file but after seeing how to get into safe mode in Win 10 I'm not so sure if that's a good idea. I haven't tried it yet and I don't know if safe mode in Win 10 allows you to view files and folders. I've downloaded other exe's and deleted them, this makes no sense.
