    Since a few days, I've notices the one of my cores is running at near 100% usage all the time (build 7068 on Thinkpad T61p). Seems to be the SearchFilterHost.exe, it uses in average 45% of processor power, according to the resource monitor.

    Normal? Any suggestions?

    Just wrote in another tread about RAM-usage, but found my post would fit better here:
    Didn't find Superfetch in services... But found another thing that annoyed me earlier: Windows Media Player Network Sharing Serivce. I've noticed in the Resource Monitor, it uses plenty of CPU-power. Turned it off, but didn't see any significant difference in performance.

    But the by far most CPU-power consuming service is the SearchFilterHost.exe, usually it uses 80-90% of the one of my cores, often maxing out on 100% usage. At the same time the other core is working on 40-60%. Has done this for weeks now. So the "normal" CPU-consumption is for the SearchFilterHost alone 47% in average (overall CPU-usage for both cores: 65-75%).

    EDIT: Just found the Superfetch-service and disabled it... CPU still running on around 70%.

    Solution? Don't know, maybe I shouldn't have upgradet the last time (from 7022 to 7068), but done a clean install? Wait for the RC and new clean install with that? Still don't know, whether this would do the trick - I've seen this 'phenomenon' earlier on other systems, XP as well as Vista, so maybe it's something we have to live with on certain Windows systems?

    Just upgraded to 7077 - sill the same load on the processors.

    Planned to attach screenshot of Resource Monitor and Taskmanager, but don't know how to... Do I have to upload the picture somewhere else and then insert the url for it? Better find out somewhere...

    Just found out about attachements... So here screenshot of Performance Monitor and Taks Manager with the relevant figures (processor- and memory usage).

    As seen in the Task Manager, my Outlook uses a large amount of RAM (unless it never reaches much more than 1,5 out of 2 GB), due to the large pst-file (maybe I should clean up my inbox). But as mentioned, still plenty of reserve to take from.

    Biggest problem is the SearchFilterHost.exe, using up all the power of the one CPU-core. Running on almost 100% all the time, when I suspend it, CPU Usage for both cores drop to 15-25% - significant drop, seen in the second screenshot attached.
