Hello all, Every so often I check my performance index in Control Panel/System/re-run assessment. My current index is 5.9 Just recently my re-run assessment stopped at the final stage when it wanted to check the speed of the CPU. I get a warning message that the CPU data exchange speed can't be checked. No reason given. For some reason I looked at my Resource Monitor and found that both the Microsoft Software Protection Platform Service and the Microsoft Office Software Protection Platform Service have been suspended. I'm using an OS loader and MS Toolkit. I'm assuming that's why these services have been suspended in the Resource Monitor. Can anyone shed some light on this issue for me. I'm intrigued by this kind of stuff. regards all.
