The problem with searching the ways so far is jpeg files can be .jpg or .jpeg and there are still gif, png and a whole host of other image formats. Still it is a semicolon to delimit the search (you type "*.jpg;*.png;*.gif" and so forth).
Simple way:
Search box (I am going with XP here). Advanced search naturally.
leave the box blank or *.*
Make sure it searches local drives (usually c:\ but you should have the option to do all the drives)
Check subfolders, system folders......
Hit search
Wait about 30 minutes probably (lots of files)
View -> details (I suggest everyone uses details).
You should have the option to view by various methods. Date modified is best (date created can be transferred across when making a new file), if it is not there then right click and add it (it may be under "more...")
Even simpler way. It should have the option to use dates in the search box. Use that with the same concept as above.
