Recover Files with Shadow Copies on Any Version of Windows Vista

ok i tried all of them im not sure how irfanview could of help though unless im using it wrong but the shadow explorer almost had it but the dates only went back to the 15th (tried on the 18th) so i did some research and it is pretty much like system restore and i have auto restore dates on the system restore set so it overwrote the one i had on the 6th which woulda worked. so i think im screwed now. thanx neways guys
