I've had this desktop awhile and need to reinstall the operating system to fix some things but I do not have a disc to reinstall with, I have all of the codes I would think I would need to get an email with the iso download link, Product Key, Service Tag, Express Service Code.
But since the warranty has long ran out I cannot do email support. Can someone help me out with this?
You can Download a Windows 10 TH2 .iso from Microsoft and clean install with your Windows 7 OEM product key. See here for details:
