Windows Server 2008 R2 & Windows 7 SP1 Release Candidate (RC v.721)

This morning I opened up an email from Microsoft UK entitled ‘TechNet Newsletter – 28 October -  Windows 7 SP1 RC | SQL Server 2008 R2 Migration’ – the main interest for me here is the SP1 RC, not so much the Windows 7 reference, but as Windows Server 2008 R2 and Windows 7 x64 share the same codebase this Service Pack is immediately applicable to the server O/S also.

A couple of months ago I’d posted on SP1 beta (, and having suffered a few minor issues of running a service pack beta I was keen to upgrade.  The main issue experienced was on my test Hyper-V Server R2 build and VM’s loosing external network connectivity under high load/stress requiring the host to be restarted to resolve – not ideal for the a production domain controller, my main Windows Home Server and my Vail test box..


Anyway back to SP1 RC..

there are 3 methods of install… ISO image/DVD, architecture specific executable, and via windows update (with a modification/additional code)

If you have the SP1 beta installed you must first uninstall it before attempting SP1 RC install, I’d recommend wusa.exe /uninstall /kb:976932 as this covers both Server Core / Hyper-V Server and full installations.


Windows 7 x86 upgrade via Windows Update
