Microsoft said problems discovered during testing are prompting it to delay a planned Power Pack 3 update to the Windows Home Server product.
The software maker had hoped to release the update ahead of Windows 7, but said in a blog posting this week that it has had to delay the release until later this year.
"As with past software releases, our team will not ship the official final release of Power Pack 3 until the community has validated our work," Microsoft said. "We expect to deliver before the end of the year."
Although Power Pack 3 is designed to offer improved compatibility with Windows 7, the software maker discovered during testing that in some cases there were problems backing up data with Windows 7 PCs in conjunction with home servers.
The initial release of Windows Home Server also faced issues including, most notably, a bug that caused data to become corrupt in rare circumstances. That issue was addressed in the first Power Pack update.
