Not sure if it will help this particular issue, however it appears you are using a release candidate edition. It might be worthwhile upgrading to the final release, available at – Graham Wager Nov 3 '12 at 14:49

Try to increase the Virtual RAM for VMWARE as win 8 is strong UI based OS it takes memory resource.Increase in the Virtual RAM from VMWARE configuration can help you..

This is a VS addin/extension called PerfWatson (as the dialog shows). Apparently MS have been using the data it sends back extensively in order to improve the performance in VS. In the non-Express versions of VS you can uninstall it if you want by going to the "Extensions and Updates" item in the Tools menu - but I'm not sure if you have that ability in the Express version. You could, of course just ignore it.

It used to come up pretty much every time I ran VS in my VM but once VS was loaded it ran fine. I did, however, uninstall it in the end.

As for the cause... well, it thinks that VS should have loaded quicker! Perhaps giving the VM more RAM may help - but it might not.
