[轉][教]解決svchost.exe吃掉所有CPU資源的方法

一、首先檢查系統服務的狀態。
1. 點「開始」–>「執行」，輸入「services.msc」後按「確定」。
2. 在服務「Automatic Updates」上點二下。
3. 點選「登入」頁籤，確定登入身分為「本機系統帳戶」且「允許服務與桌面互動」“沒有”被選取。
4. 確認服務已在目前的「硬體設定檔」中被啟用，如果沒有，按下「啟用」按鈕。
5. 點選「一般」頁籤，確定「啟動類型」為「自動」，然後按下「啟動」按鈕以啟動服務。
6. 對「Background Intelligent Transfer Service (BITS) 」服務重覆2 ~ 5的步驟。

二、接著重新註冊Windwos Update的元件。
1. 點選「開始」–>「執行」。
2. 輸入「REGSVR32 WUAPI.DLL」後按Enter。
3. 當看到“DllRegisterServer 在WUAPI.DLL成功” 的訊息後按下「確定」。
4. 重覆上述步驟重新註冊下列元件
REGSVR32 WUAUENG.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL

三、最後更名可能已損壞了的Windows Update暫存目錄。
1. 點「開始」–>「執行」，輸入「cmd」後按「確定」。
2. 在命令提示字元中鍵入以下指令。（若出現錯誤訊息請先重開機後再報執行一次）
net stopWuAuServ
2. 點「開始」–>「執行」，輸入「%windir%」後按「確定」。
3. 找到「SoftwareDistribution」並更名為「SDold」。
4. 點「開始」–>「執行」，輸入「cmd」後按「確定」，並在在命令提示字元中鍵入以下指令。
net start WuAuServ

>>在執行到 net stop wuauserc時好像不行...

Please roboot your computer before doing this.
Or you can tpye "net start wuauserc" first, then "net stop wuauserc".

>>請問各位大大%windir%為啥這一個我都不能點?!錯誤謝謝唷

%windir% is same as the folder at c:\Windows

>>修改後，還能ｕｐｄａｔｅ嗎？

Yes!!!

>>有辦法恢復之前沒設定的ㄇ

Just doing backward.
1. Run "net stop wuauserc"
2. Change folder name back to original name.
3. Run "net start wuauserc"

>>請問為啥我在步驟三的其中改SDold 都不能改名

Because you didn't stop the wuauserc service.

>>那spoolsv.exe過高怎麼辦?

I think that's a related printer problem.

>>重開機後還是會有svchost.exe阿@Q@

Of course. 一.一|||

>>常常explorer.exe 100%

There are too many reasons can cause this.
There is no single solution for this. you need to find out what cause the problem is first.

>>不知是否還有別的方法!?

Sorry! This is the only soulation that actually works.

>>我是system idle process cpu都80以上請問是啥原因呢
