Why is the svchost 100% CPU use Bug Not Being Fixed By Microsoft?
Hi,
What in the world is the deal with svchost running at 100% and preventing updates? This has hit all my XP machines at about the same time. It is not malware (I've run exhaustive AV checks) but apparently a bug that for some reason MS is not fixing(?) Or what? I have tried everything, all KB patches, I even did a fresh reinstall on one machine and it's worse than ever on this machine. To not be able to update is a mission critical issue. What please is going on? I know XP support ends in a few months but something glaring like this must be fixed. Plus, after failed attempts to update, svchost continues to use 100% and some services slow to a creeping halt! Please, does anyone know what's going on? Thanks |

Plus, after failed attempts to update, svchost continues to use 100% and some services slow to a creeping halt! Please, does anyone know what's going on? Thanks I have a theory. The Windows Update server at Microsoft, keeps a manifest of updates to be offered. Your client machine queries the manifest. Every time that a new Internet Explorer security patch shows up, the wuauserv on the client computer, begins to evaluate the chain of previous updates. Like, what updates does this update replace ? The chain is very large for Internet Explorer, and the wuauserv goes off in a CPU loop for more than 30 minutes. (This is a bug, not a feature - it should only take a second.) Eventually, the software comes up with an answer, and the CPU usage stops. Since Windows Update gets queried on at least a daily basis, you will see this "calculation" over and over again. Very bad on a single core computer. If you manually go from machine to machine, and push out the pending Internet Explorer update, then the next time the machine queries Windows Update, there is no chain to compute for Internet Explorer. Then the CPU usage should stop. Until the next Internet Explorer update shows up, which is roughly monthly. The last update I downloaded manually from Microsoft, was WindowsXP-KB2898785-x86-ENU.exe . I installed it, and my Windows Update 100% CPU stopped. The date on this is Dec.10, 2013. You can get some files here to test the theory with. Try updating a machine with the CPU loop, and see if the problem stops. http://technet.microsoft.com/en-us/s...letin/ms13-097 Installing that is a workaround, not a solution. The very next time a different KB comes along for Internet Explorer, the thing will go into a CPU loop again. Something in wuauserv needs to be fixed. Will Microsoft fix it before April ? Only if it affects some OS other than WinXP. Paul |

Only the customer was viruses to the gills. Every time he tried to do anything network wise, svchost went nuts. I left him scanning. He hasn't called me back. Did your customer occasionally lose his mouse too? -T Maybe somebody here can post at what point, and with what specific update, this whole thing started happening. And then those who want to install updates can just decide to install all the updates up to that point, and just leave it there? Yes, I know, that precludes getting all the future updates to allegedly secure your machine, but is this lurking svchost issue (and all the others reported in here) worth all this aggravation? Last time I had a svchost issue, I could never track it down (since svchost hosts so many services), and I was only able to get it "fixed" by updating from XP SP2 to SP3. And that was even with some help from Paul. :-) |
