What is this GRPCONV.EXE ?

Installed V2 of CSC and received a pop-up from D+ for grpconv.exe. Under properties it says it’s a windows product group converter. It was downloaded to my computer with the download of CSC V2. What’s the story with this?

It’s a legitimate file and it’s been in every version of windows since the very early days. See here:


Thanks for the info… Never had D+ pop-up for this file. And my mistake, it did not download and install when I installed CSC V2 but it did get modified during the installation…
