But install Google Desktop Search and you’re likely to lose the global shortcut key of Win + F, and there’s no obvious way to get it back.

Here’s how.

1. Open Control Panel.
2. Find Default Programs (you may have to set Control Panel to classic view to find it.)
3. In there, open Set Default Programs.
4. For Windows Search Explorer, click on Set this program as default.
5. Click OK.
6. You’re done.

 The Master List of New Windows 7 Shortcuts – Windows – Lifehacker

(This was written in frustration at the lack of useful guide to making searches in Windows Seven. Some of the text is drawn from this Dummies page. Update: Also I’ve taken some stuff from this excellent article at Windows 7 News.) 

These search parameters help you narrow down what you’re looking for in Windows Seven’s Explorer (to jump to the search box in that program hit F3. From anywhere in Windows Seven hit Windows key ( ) + F) to open a new search window.

How to use filters

These filters can be used in conjunction with, or separate from, text search terms. If you just start typing a term, Windows will start looking for all files (and folders) that include that name in the file name, the folder name, the contents of the file and its metadata (tags and whatnot). Although the idea of searching as you type is a good one, it can be frustrating if you need to correct something you’ve written.

Date

Type date: (or one of the options below) and, while it may take a little while, a drop down menu should appear that will allow you to specify the date of the file you’re looking for.

Date Modified: Search for files based on the date they were last modified.

Date Created: Searches according to when the file was created. You can select the date (or a range of dates) from a mini-calendar that appears.

You can also be less specific and choose: A Long Time Ago, Earlier This Year, Earlier This Month, Last Week, Earlier This Week, or Yesterday.

(See also Date taken below.)

Boolean terms’

You can also filter use some boolean terms like AND, OR and NOT, as well as wildcards:

suharto AND indonesia

suharto NOT indonesia

*harto NOT soeharto (any word ending with ‘harto’ except ‘soeharto’)

“pak harto”

Size

Search for a specific file size by typing its KBs or MBs in the search text box. Or, you can search by various size ranges via the drop-down menu:

Kind

Search for files of a specific type as selected from the drop-down list that appears when you click the Kind option. What’s frustrating with this is that there’s only kind of Document file (i.e., you can’t use this filter to narrow it down to spreadsheets, say, or word documents. For that you need to use Type below.)

Type

Searches based on certain file types by extension, such as .pdf, .jpg, or .docx. (Waiting for the computing filter to run on this one takes a while. I wouldn’t bother.)

I don’t know whether this is true or not, but the syntax needs to include an = after the colon, like this:

type:=.doc

Leaving it out seems to include files of other types in the list:

Name

Searches by filname. You can enter all or part of the filename in the search text box after the Name filter.

When you don’t know all of a filename, you can use the asterisk (*) to stand for one or more wildcard characters in the filename and a question mark (?) to stand for individual wildcard characters.

Tag

This filter lets you search for a file by the tags assigned to it. Enter one or more tags after the Tags filter in the Search text box. If you’re not sure of the tags just wait for the drop down box to appear (it should say something like computing filters… prior to that)

Author

Search for file by a particular author. Enter an author name after the Authors filter in the Search text box or select the name from the drop-down list that appears. (This filter is called Artists when searching audio files. See below for looking for specific songs)

Filters specifically for multimedia files

Pictures

Date taken: Searches for photos by the date they were snapped.

If you have added whatever folders you’re using for your photo (or video)  files to the Pictures (or Video)  Library, then it’s probably easier to look for a photo (or video) by first clicking on Library, and then clicking on the search box, now called Search Pictures (or Search Video).

You’ll notice that the drop down menu now includes search filters relevant to photos (or video):

Music

Length: is another parameter you can use to search for an audio or video file by its relative length. You can enter the exact length or select one of the Length options that appear in the drop-down list.

If you have added whatever folder you’re using for your music files to the Music Library, then it’s probably easier to look for a song or artist by first clicking on Library, and then clicking on the search box (now called Search Music). You’ll notice that the drop down menu now includes search filters relevant to music:

Set up Thunderbird on your new computer/drive and launch it.

Don’t bother importing anything. But you need to get Thunderbird going to set up the AppData folder. This is where everything gets stored.

Close Thunderbird.

Now find your old Profile folder. The easiest way to do this is to copy the following into your Explorer address bar:

C:\users\[User Name]\AppData\Roaming

(clicking on the address bar will change the appearance from

to the more familiar:)

If, like me, you’re moving from one partition on a drive to another, or your old stuff is on an external drive, you may also need to change the drive letter.

Then replace the [User Name] with your old user name (and remove the square brackets.)

This should take you to the following folder:

Go into the Profiles folder and find whatever folder in there has the suffix default:

Now open another Explorer folder (right click on the folder icon in your taskbar and select Windows Explorer:)

Do the same thing as before, pasting in the above text and replacing it with your new Thunderbird location. Find the profile folder. There should be an existing default folder in there.

Now drag the old default profile folder you found above into the new Profile folder. (This should keep a copy of the old profile folder, so long as you’re moving between drives. Otherwise you may want to make a backup copy first.)

You should now have two default folders together in one folder.

Now select the new default folder that Thunderbird has just created, hit F2 and then rename its suffix from default to old:

Now rename your old profile folder to the new profile folder, with the suffix default (you might just want to copy and paste the name by hitting F2 and the selecting the text, hitting Ctrl/c etc):

Now fire up Thunderbird and you should see your old emails, settings, and plugins, all working normally.
