故障描述：
用戶原來安裝的是WPS，因爲和單位某些業務系統不兼容，卸載掉後換裝Office2007，結果在Word裏插入Excel對象會跳出下邊的提示：
在Powerpoint裏插入Excel對象會跳出下邊的提示：
注意看在Word裏插入Excel對象時有“ET”字樣，這就確定了絕對是WPS導致的
解決：
網上搜索了很多方法，都無法解決。
按照錯誤提示，猜想可能是註冊表中某些值還是WPS的，沒有改過來導致的，於是去註冊表中搜索，發現：
HKEY_CLASSES_ROOT\CLSID\{00020810-0000-0000-C000-000000000046}到HKEY_CLASSES_ROOT\CLSID\{00020833-0000-0000-C000-000000000046}是插入Excel對象需要提供的一些數據，比如圖標、文件後綴名、文件打開程序等
HKEY_CLASSES_ROOT\CLSID\{000209FE-0000-0000-C000-000000000046}到HKEY_CLASSES_ROOT\CLSID\{00020907-0000-0000-C000-000000000046}是插入Word對象需要提供的一些數據
其實這些註冊表項就是Office插入“對象”列表中顯示的內容。也就是下圖紅框中的內容
下邊列舉出其中一個插入.xlsx文件對象相關註冊表鍵值

@="Excel.Sheet"這上邊最重要的其實就是LocalServer32和LocalServer，但光改這2個值是沒用的，因爲其他值都是有關聯的。所以從正常電腦的註冊表中導出這些相關項，刪除故障電腦註冊表中這些相關項，將正常電腦的REG導入故障電腦中，問題解決。
需要注意的是：必須要刪除再導入，否則還是有錯誤，因爲WPS加入了多餘的鍵值，不刪除直接導入這些WPS鍵值還是會導致錯誤提示
