Win7 the computer's control panel can not find the software to uninstall what to do?

Computer naturally need to install a lot of programs and software, if you run into the back does not need to use, we can directly unload them is, in general, we uninstall software can be done in two ways, one is through anti-virus software, security guards and other Third-party software methods to uninstall, There is a direct control panel in the computer to uninstall, but recently a friend said, in the Win7 pure version of the control Panel, can not find the need to uninstall the software, so that software can not uninstall, this is what is going on?

Generally speaking, there are two kinds of reasons for this failure:

1. Software is green software, that is to say, the software is not required to install can be used, the operation of this software is the same as the General Program service, is double click to open, but in fact, it is not installed on our computer, so we can not find in our control panel, if you want to remove the software , just right click to find its path, and then delete the entire folder on it.

2. The software is not written to the registry, such software is required to install to use, but will not be written to the registry, so in the control Panel can not be associated with the file, so it can not be unloaded in the control Panel, this software uninstall is relatively troublesome, if the way to delete the folder directly, You may need to use Third-party software to uninstall it.
