Microsoft Corp. said fixes for security flaws present in most processors may significantly slow down certain servers and dent the performance of some personal computers, the software maker’s first assessment of a global problem that Intel Corp. initially downplayed.

Microsoft’s statement suggests slowdowns could be more substantial than Intel previously indicated. While Intel Chief Executive Officer Brian Krzanich on Monday said the problem may be more pervasive than first thought, he didn’t discuss the degree of impact -- only that some machines would be more affected than others.
