I, too, was frustrated when I first got my W7 laptop and wanted to search filenames. I'm no expert on W7 but I depend on being able to search filenames frequently as part of my job so I REALLY missed the Advanced Search window from XP. [HINT: Microsoft
could you PLEASE bring the Advnaced Search Window funcitonality with two fields for searching either filenames or anywhere in the file!]
Looking in W7 help (F1) didn't bring up what I needed until I looked at an external site and found out that MS calls their advanced search functions by the moniker "AQS" for Advanced Query System. If you search for AQS you should be able to find more
info on the advanced search functions.
I was a little turned-off at first by the amount of typing required but finally having a method that worked helped to ease the pain.
If you want to limit your search just to filenames, type something like
System.filename:~="cfg" into either the W7 search window or the Windows Explorer search window.
I have not found a definitive guide to all the details of AQS (Microsoft, it would sure be nice if you could publish details of AQS on your support site :-)) but here are a few of the logic symbols (the info was pulled from W7 help on Advanced Search):
If W7 did not find what you are looking for, or if you know which drive or folders you would like to search and would like to limit it to that drive, then after your first search you should see the "Custom" icon appear under a line below your search
results. Click on it, then click on Documents and then Navigate to the drive you want to search and check the checkbox next to it. This section of W7 works very sweetly since if you check a drive then click the triangle next to it, it lists all the first-level
folders with each of their boxes checked. If want to exclude one or more of them you just uncheck the boxes of the ones you want to exclude.
Well, Happy Hunting! I hope this helps.
May God bless you with His best!
