最近處理了一個少見的問題,當開啟IE後,iexplorer.exe的使用率就直接飆上100%,共試過下列幾種方式:
- Disable all add-ons
- Restore IE default settings
- Clear all cookies and cache
- Turn off antivirus software
- Uninstall IE8,Downgrade to IE7
- Open only one blank page
- Enter Safe Mode
All of the above methods were ineffective,Then log in as an administrator,After logging in with a different account,The problem did not occur again,Then proceed to the UserProfile。
First, create a new UserProfile,Copy the items from the original profile in order,期間不斷的登出登入做測試,最後終於找到問題檔—UsrClass.dat,此檔位於"C:\Document and Setting\ID\Local Setting\Application Data\Microsoft\Window"。網路上對於此當的資訊並不多,查到的僅是很籠統的說明是使用者設定檔,但我將其改檔名後,並無發現有任何設定值跑掉,但卻可解決IE loading滿載的問題。
開啟IE造成CPU使用率滿載的原因有很多種,如果試過上面幾個方法皆無法解決的話,倒是可以對UsrClass.dat下手試試。
