差不多我用到的大部分代碼都是從上面cv（Ctrl+c---->Ctrl+v）下來(lái)的

1、首先解決The context is partially valid. Only x86 user-mode context is available. 

具體方式是hookKdpTrap

2、 防止安全組件加載失敗

SharedUserData->KdDebuggerEnabled = FALSE;  //防止安全組件加載失敗，SharedUserData這個(gè)是一個(gè)導(dǎo)出的全局變量直接寫就行

3、XP會(huì)清零KdDebuggerEnabled

這里本來(lái)是打算做一個(gè)定時(shí)器，但是還是會(huì)導(dǎo)致TesNginx.Sycccccccccccccc出現(xiàn)藍(lán)屏，所以只有手動(dòng)的去修改

4、斷鏈隱藏 kdcom，防止kdcom內(nèi)存被清空導(dǎo)致和windbg通訊不了

5、XP會(huì)檢測(cè)KdEnteredDebugger，如果是1就直接藍(lán)屏

處理方式是讓他去找其他位置(PUCHAR)KdEnteredDebugger + 0x30;  //據(jù)暗中觀察，+0x30 的位置恒為0

做完這些之后基本上就能夠下斷點(diǎn)了，但是其實(shí)還是有問題（由于hook了系統(tǒng)函數(shù)有一定的幾率會(huì)觸發(fā)109錯(cuò)誤->PathGuard，一開始我也分不清楚，后來(lái)慢慢的也了解了）

之后放上一張過了圖片

最后把代碼也帶上吧，.asm文件很簡(jiǎn)單簡(jiǎn)單的inlinhook就行了
