GWX Control Panel 1.7.4.1

What's new in this version:

- Removed a misleading alert that was appearing on some computers with "clean" Windows installs that had not yet encountered Windows 10 symptoms. This was a dialog box I had added while I was testing a fix I had implemented in version 1.7.4.0 but ended up not needing. The alert was harmless, but wasn't supposed to appear in the final release, so now it's gone
