OK, I have Win7 Ultimate OEM installed on a Gigabyte board. Moded Slic 2.1 BIOS (Dell)with Dell cert and serial installed with Daz loader. I admit I am kind of paranoid now with the KB971033 patch out there now. I hid the update and have not had the ballz to run it. Anyway it appears I can get a legit retail Ultimate key. Is there anyway to 'convert' my OEM install to Retail (and insert the new key) without a reformat? Thanks!
