Random Missing Open Type fonts in Windows 7

So after upgrading to a newer (for me) computer with windows 7, I'm having an issue similar to 2012 when the Windows update made some open type font inaccessable in Corel but they are still in the fonts folder. I looked up the old info regarding the update and removing it, & found that I had the offending update file. Removed it and rebooted and still no Open type fonts. Is there anything specific to Windows 7 that I'm missing? (The last time I was on XP)
