Hi Folks –
Just want to make sure you know we are actively following up on the comments posted on the svchost/msi issue. We are working on reproducing the reported performance issues on various systems in our labs. We will keep you posted as to the findings.
I also want to provide some clarification with install instructions for both the new client and the MSI fix, as well as upcoming available automatic distribution options, and the performance expectations after the MSI fix and new client are installed.
Build 0374 AU client/ WSUS 3.0 client:
While we are engaged in a world-wide deployment of the new AU client (build .0374), this staged deployment is occurring in a wave which we expect to complete by early June. This means that for AU users, the new client bits will just automatically self update when visiting the site before mid –June, and for WSUS users, you will be able to download the bits after 5/22/2007 (or upgrade to WSUS 3.0 now).
To make the client available earlier vs. waiting for the duration of the world-wide roll-out, we released the client in a ‘stand-alone’ form which you can download from the Download Center now. The version of the client is 0374 – and can be installed directly from:
Further instructions can be found in http://msdn2.microsoft.com/en-us/library/aa387285.aspx
Please verify on your systems, the client version here is: <windows dir>\system32\wuaueng.dll is 7.0.6000.374
To make sure you have the latest MSI fix in KB927891, make sure your MSI.dll binary version for supported platforms are exactly as documented under files in:
This MSI fix will be available via MU/WU (and there by WSUS) by late May early June.
Expected results: It’s important to note that with the MSI fix and the new client installed, the CPU may still go near 100%, but the system should still be responsive and not lock up. If another task requires CPU cycles they will be shared, but if the system is idle, MSI will use the full cycles available. If a task is running at the same time as MSI, the system may be slightly slower, but should still be responsive during this time. Key to remember the MSI fix and the new client address unresponsive or locked systems. CPU spikes during some scans are expected, machine unresponsiveness is not. If your watching the process monitor, you will still see 100% CPU during some scans and this is expected behavior.
Next steps for problem systems:
If, after checking these installations, and reviewing expected behavior, iyou are still experiencing this issue and have a system which we can remote into, or obtain logs from, for further investigation, please contact me directly at firstname.lastname@example.org. The windowsupdate.log from the system experiencing the performance issue would be helpful information as well as full system description of hardware, platform and additional programs installed and running.
PM, WSUS CPE
