Vista Permanent Delete & Registry

1. Not really no as those files could be recovered, whereas applications such as East-Tec Eraser will use random multi wipeing techniques to scramble the deleted data, The Windows Recycler will just mark the deleted datas headers as avaiable to write on,

2. CCleaner http://www.majorgeeks.com/download4191.html



Also CCLeaner will allow you to not only clean the registry and all the associsated temp and internet files, but in its Options > Settings menu it allows you to set a multi pass secure erasing option, this does similar job as East-Tec Eraser, so when you run the cleaner and have Recycle Bin checked to clear its contents it will sercurely erase the contents ( note it may take a while if you have it on 3 or 7 passes )
