ちょうど関連している次を受け取った 私が過去に約書いたSVCHOST問題…

MSは解放した「マイクロソフトの保証状況報告(927891) -実際に直接安保問題ではない、しかし実際に人々は重大な保証か他の更新を得ることを防ぐかもしれない住所心配Windowsの取付人(MSI)のための苦境」。

前に述べられるように、それは含むMS KB 927891を- 「アクセス違反の間違いを受け取り、Windowsの更新またはマイクロソフトの更新からの更新を取付けることを試みるときシステムは無理解になるようであるかもしれない記事(8.0)の「、「この苦境がWindowsの更新の顧客のソフトウエアアップデートを含んでいる2部の苦境の1つの部品であることをそして現在の修正示す。 これらの更新は2007年5月および2007年6月以内にWindowsの更新を使用して自動的に配置される」。

再度、この更新は2の1つ適用されるその必要性十分に問題を扱うためにである。 他の更新はであるMS KB 932494から利用できるWindowsの更新の顧客ソフトウェアの版3.0 「更新のためにスキャンするか、またはWindowsの取付人を使用する適用に更新を加えるのに自動更新を使用するとき、Svchost.exeプロセスを含む問題を経験する“.

以前は(ここに そして ここに)、私は特定の焦点との共用サービスの隔離についてそのサービス(wuauserv)がNETSVCS SVCHOST.EXEの例で普通動かすWindowsの更新の自動更新で自身のプロセスで動くように書いた。 これ一度することができる1つの事はサービスがCPUの100%年を消費することを巻くとき、システムが無理解にならないように堪能プロセスの優先順位を下げることであるである。

Since we’re dealing with a service, setting the priority of such a SVCHOST.EXE process can become problematic - the service may already be running, or, because it is a service, it is not started as non-service processes are, so one is not able to use START / [LOW NORMAL HIGH REALTIME ABOVENORMAL BELOWNORMAL] to impose a priority when the process starts. One can use a utility like Task Manager or Process Explorer to set the priority of a process on an ad hoc basis, but when the service restarts or the system reboots one has to remember to set the priority again.

Though not an ideal solution the following scripts (VBS using WMI, and PowerShell) can be used to set the

Previously (Part 1: Introduction - What’s using my CPU?), I kicked off what I expect to be a multi-part series on determining what is causing excessive CPU consumption, outside of the normal “which process has the highest value in the CPU column in Task Manager”.

Before I get into things, a little bit of background may prove useful or mildly entertaining. Over on “Sysinternals Forums”, there were recently two similar problems that both involved excessive CPU utilization that was not attributable to a specific process. I became involved in both problems and attempted to use similar techniques to get additional information with the hopes of ultimately being able to pinpoint the problem. What may make this mildly entertaining is that in both cases, there was limited or no success in detetmining the cause of or solution to the problem. In the end, one problem was resolved by disabling the floppy disk controller, and the other problem appears to be as of yet unresolved. (In the latter case, the poster did admit that the system was experiencing hardware problems - the chipset fan was dying and there…

In the past, I’ve written about both high CPU utilization by SVCHOST.EXE as well as the 0×8ddd0009 Windows Update / Microsoft Update error, so I thought I would mention this…

MS KB 932494 (When you use Automatic Updates to scan for updates or to apply updates to applications that use Windows Installer, you experience issues that involve the Svchost.exe process) references problems that are addressed by MS KB 916089 (FIX: When you run Windows Update to scan for updates that use Windows Installer, including Office updates, CPU utilization may reach 100 percent for prolonged periods) and MS KB 927891 (You receive an access violation when you try to install an update from Windows Update after you apply hotfix package 916089). However, even after applying the patch associated with 927891 (which replaces the patch associated with 916089), 932494 indicates that the following problems remain:

1) Certain 100 percent CPU issues are still present when you use the Svchost.exe process.
2) An access violation may occur in the Svchost.exe process.

I (as well as others) have speculated in the past that 916089 (and its succedent patches) can also help with the 0×8ddd0009 error…

Recently, I have been involved in attempting to diagnose problems with excessive CPU utilization. Often times, this type of thing is relatively easy to identify - at least as far as pointing the finger at the thing that is consuming CPU cycles. Task Manager can be used for this - simply sort the “CPU” column in descending order and note the process that is at the top of the list. One can use a similar technique with Process Explorer.

In the past (here and here), I’ve given examples that demonstrate various techniques that can be used to try to determine what a process is doing when it is consuming so much CPU. Sometimes, you can do something about it - if you have the debugging symbols, perhaps there is something in the stack of the thread or threads in the process that is consuming the CPU that will lead you to some setting, feature, or configuration piece that can be manipulated so as to avoid the problem. Or perhaps just knowing the module name is enough information to identify the problem software - a recently installed add-in / plug-in, or a new utility,…
