Microsoft released KB2607070 to resolve a software deployment issue with SCE 2010 managed Windows 7 SP1 PCs. I first noticed this with Office 2010, and it appears to have affected the distribution of other software packages.
An update has been released to resolve issues where System Center Essentials updating Windows 7 SP1-based computers with locally published content may fail with error 0x80070570.
When you locally publish updates through System Center Essentials and then attempt to download and install those updates to a Windows 7 SP1-based computer, those updates may fail with error code 0x80070570.
