While trying to run the LSI Predictor on one of my servers I was getting the error message

Please install Microsoft (R) Windows (R) Performance Analyzer Version 4.8.7701

It took a while to nail down  what I actually needed to get this installed however the solution is hidden away in the Windows SDK (the link is for Windows 7 but the same applies to Server 2008 R2).

So get that installer downloaded and follow the steps below and you will be able to analyse your servers HDD performance with a pretty nifty tool.
