Windows 7: CPU Usage 100%

Try that XML trick see if that works.

Also is windows automatically managing the page file? If not, let it.. if it is, I would try manually changing the page file to 5 gigs.

How do you do this?

You can turn this setting on and off by right-clicking the Computer icon, clicking the Advanced System Settings link, then clicking the Settings button under Performance, then the advanced tab.

My CPU is at 0% during idle, and page file is 4934MB

Please note, I have 4 gigs of RAM so my paging file is larger then someone with less RAM (yes these numbers are seperate), also, please let us know your hard drive size, so we can determine if you are able to have the required space for the paging file.

Finally, I would suggest this:

Disable the .XML file extension from being indexed in the Indexing Options control panel.

Good luck guys.

As you suggested, I removed my previous adjustments and adjusted the pagefile (manually) to the recommended setting of 4221 MB (why the system doesn't automatically set the page file to the recommended setting is beyond me) and the CPU usage dropped substantially. Core 1 alternates between aprox 60% and 95% about once per second, and core 2 alternates between 8% and 24%. I'm not sure how to change the indexing options, but I'll keep trying. Thanks!

Hi, sorry,

Just right click on your hard drive(s) properties and at the very bottom it should say "allow files on this drive to be indexed etc". Uncheck it.

It only makes the built in "search" function of windows faster.. if you do not use that feature too often to look for a file (I know I do not) then you do not need it.

You can manually set that not to index xmp files, but turning it entirely off is probably more productive.

I'll give it a try. Thanks!

Sadly, i started having the same problem.
I'm using Windows 7 64x build 7057 on an Athlon 64 x2 4000+ ; 2x1GB RAM and a GF8600GT.
I tried to disable the HD Audio devise, the Gadgets and .xml file indexing. Also I checked for viruses. When I used the Minimal Safe Boot Option the problem wasn't there.
The problem itself occured when i used verifier.exe to check if all drivers are OK. The verifier asked me to reboot and when I did the CPU Usage was hitting the roof.
Suggestions?

I have an even weirder one.

My CPU monitors say 100% for Core1, bounces around between 50 and 100% on Core2... but when I check Task Manager, there isn't a single process above 5%. The usage certainly doesn't total even 30%.

I've disabled drivers for devices that are not in use currently (SATA PCI card, ATI video capture card, and all USB card readers).

I've disabled indexing, which took an incredibly long time.

I've updated all drivers for existing hard drives and the controllers.

I'm still at 100%, often on both Cores.

I had the same 100 percent cpu and after disabling HD audio drive like the others my cpu has dropped and stayed at 2% idle!!! Hooray!! I had trouble finding this because it wasn't listed under my audio section, but instead a ways down under total different category. Many thanks for who ever found this out!

I have to say I really like windows 7 and am prepared to buy it next month. Only real issue so far has been cpu usage after installation and my Norton Gaming edition 2009 is incompatible at the moment until release of final version.

just watching the cpu monitor it stays right at 50% as it scrolls by with little bitty jumps now and then. would hate to see it if I was actually using any program that was demanding. guess I better look at this in vista 64 bit and see if its the same.

is there anyplace in windows help that explains what all that means in those meter boxes? network frequently jumps to 100% and disk to 100% as well.

thats way high Im running half the computer with less mem and zero page file FF has 8 tabs open and search is indexing and cpu is at 24%
should be like your vista specs
