We all want to make Microsoft happy don't we? So lets put values MS expects in there. Values modified by the patch: Type 0: Bit 2 of byte 2 must be 1 Type 1: Manufacturer/product string should not be empty Type 3: Manufacturer string should not be empty Type 4: Processor manufacturer should no be empty Max/current CPU speed shouldn't be unknown Type 16: Memory should have error correction.
