Recently I came across HeiDoc.net as a source for Win7 ISO file downloads. Are these ISO file downloads thought to be reliable?

A Win7-Pro PC I own that has problems is believed to have been set up from an OEM copy of Win7. HeiDoc seems to have two versions of each Win7 ISO: a 'regular' version and a 'COEM' version. Which version should I use?

Thanks, in advance, for any and all comments, suggestions, and advice.


I didn't find the right solution from the internet.
