如何从电脑中强力卸载软件，如果响应的文件上了，并且当时安装程序也找不到了。

我装了一个软件，我主动把这个软件目录下的所有文件全部删了， 但是它的信息在注册表中还存在，并且影响了我使用其他软件。这时我想把这个软件彻底卸载。于是我用windows自带的Add/Remove工具卸载，虽然Remove list 中有X的信息，当我click to uninstall, there is

error, because it could not find the uninstall program. I must repair it first. But I need the original install kit. It is a problem, since I could not find that.

So I download some professional unIntall tools  “完美卸载”， but no use.

Now I presume that, the X info is listed in the “Add/Remove Programs”, then there must be some install/uninstall info in the registry.

1.So I find the related info like “Direcotry/X” in the registry. (Like under “HKEY_LOCAL_MACHINE＼Software＼Microsoft＼Windows＼CurrentVersion＼Installer/Folder or UserData”,  HKEY_LOCAL_MACHINE＼Software＼Microsoft＼Windows＼CurrentVersion＼Uninstall), and delete the key.

2. Open the Add/Remove program to uninstall ‘X’. It said could not find “Uninstall kit in C:/WINDOWS/Installer”.

3. I copy a new installkit of X (Note: it is not the original one) to “C:/WINDOWS/Installer”. 

4. I try to unistall “X” again, it succed!!!!! Yeah!!!!!!!!!

Before that , I also try to unintall “X” in the safe mode, but It seems no use. I could not even use the Add/Remove program of windows.
