My original intention was to install and uninstall each legitimate software with "Total Uninstall v3.61" (TU) and never use "Add/Remove Programs" of Windows again. This worked very good for all my softwares, including installing FDISR. But uninstalling FDISR with TU was a disaster and lasted way too long. I had to stop TU abnormally. So my next procedure for uninstalling softwares will be : 1. Uninstall any software with "Add/Remove Programs" first 2. Then uninstall the software again with TU to remove possible leftovers. 3. Run my registry cleaner to remove possible leftovers in registry.
