Microsoft unleashed Windows 7 Service Pack 1 today, making it available (but not defaulted to install) through Windows Update. I went ahead and installed it on all my Windows installations, both physical and virtual. The installation through Windows Update went without a hitch.
I used the same process on each:
1. Install any pending patches (except SP1) and reboot
2. Do a full backup to Windows Home Server
3.Install Windows 7 Service Pack 1 through Windows Update
The installations took varying degrees of time, with most of the time spent downloading. My SSD equipped machine installed in minutes with the virtual machine running on it taking about 6 minutes. The other machines took longer, seeming to spend an inordinate amount of time downloading the patch files. Maybe the MS servers were busier by the time I got to them. Each machine needed 60 to 90MB of files although the message indicated up to 570MB might be needed. I keep the machines up to date with patches so it appears SP1 was smart enough to not repeat them.
SP1 is mainly a patch compilation but Microsoft says there’s a few additional enhancements:
Windows 7 Service Pack 1 (SP1) is an important update that includes previously released security, performance, and stability updates for Windows 7. SP1 also includes new improvements to features and services in Windows 7, such as improved reliability when connecting to HDMI audio devices, printing using the XPS Viewer, and restoring previous folders in Windows Explorer after restarting.
So far everything is fine, although I haven’t run everything. Anyone else diving right into the deep end with Windows 7 SP1.
