Windows Forum / Windows Vista / Performance and Maintainance / September 2008High CPU utilization with svchost.exe / dwm.exe
Been running Vista Enterprise for almost a year, with no issues. This problem just began last night. When booting my computer, I have about 1 minute after I reach the desktop before my CPU utilization goes way up. I have a Intel Core2Duo, so the rogue process takes up only 50% (appears to only use 1 core). Even so, I am unable to do just about anything (open windows, close windows, click start menu, ctrl+alt+del). The task manager (if I had it open already) will still update though. I see that *svchost.exe* is using exactly 50% of my CPU, and roughly 42MB ram. Using process explorer, it would appear that the child process of that *svchost.exe* instance is *dwm.exe*. I've disable the Aero interface, and have disabled the *Desktop Window Manager Session Manager service*, so it won't start. The CPU still goes up, only now, there is no child process under *svchost.exe*, and it still goes to 50%. I have left the computer running over 10 minutes, with no change. No hardware or software changes have been made. Antivirus is NOD32 (up-to-date, and even disable for troubleshooting). I am at a loss as to what is the issue. Any ideas?

Perhaps it's one of those bugs that Msoft can't/won't fix, so they prefer to not acknowledge its existence. > Been running Vista Enterprise for almost a year, with no issues.

I have similar problems but it mostly shows in JAVA and IE related softwares... and anything with DLLs in them... Once they started though (after a while) they seem to work fine... but IE is very sluggish... > I'm getting the same problem - see above in "Boot into molasses". > [quoted text clipped - 24 lines] > > (up-to-date, and even disable for troubleshooting).

But just lately, svchost has started taking up in excess of 65% of both processors. The only way I can fix it is to hold the power button and crash shutdown Vista. I wish MS would kill Vista and go back to XP.. at least after SP2, it was reliable. The thing that gets me is Microsoft knows from these forums that they have hundreds of thousands of problems in Vista, but they will not aknowledge any of them. Once I reboot, I kill MS Update, the Indexing service, the audio service and disable security notification. I am then able to run. I am running 100% Vista compatible components. VSTA motherboard with 2gb Ram, ATI 9600 graphics card and Athlon X2. This machine absolutely screamed and had no problems with XP64. Vista killed this machine and it runs like Windows 2000 on a Pentium I computer. > Been running Vista Enterprise for almost a year, with no issues. This > problem just began last night.
