I've started using a few of the Windows 7 gadgets (Yahoo's/Konfabulator's seem too flaky) to replace the Google Desktop gadgets. For desktop searching, I'm giving Locate32 a shot - I've just installed it.
http://www.locate32.net/ (using the latest "daily" from July).
(Via this review from October - http://www.techsuppo...earch-utility.htm - and reading about the cited "tweaks" to Winders 7 Search.)
Unfortunately, it seems to have been orphaned after September. http://locate32.net/...pic.php?f=8&t=689 Oh well.
HTH.
Cheers,
Scott.
