Microsoft prepares Windows 7 for external SP1 testing - Within Windows Similar to previous external beta service pack rollouts, Microsoft has enabled â€“ via updates you already installed â€“ a beta â€˜candidacy checkâ€™ within its Windows Update software. Just like Windows Vista, a registry key and value pair need to be added prior to being authorized to download the new software. Although Iâ€™ve documented the required key and value names, the valueâ€™s data (likely a GUID as before) remains unknown. The takeaway here is that external Windows 7 SP1 testing should commence soon, if it hasnâ€™t already. Tips regarding the significance of the name SPORTM would be greatly appreciated.
