Save downloads to a different directory

2011-02-14T21:23:00.000-08:00

Save downloads to a different directory.
These tips apply primarily to Windows 7

fie Windows 7 Downloads directory sounds convenient, but since few

users ever go browsing there, downloaded files may be forgotten for

days. Most browsers will default to downloading into this directory.

Firefox and Chrome users can change this relatively easily, though,

to something more convenient. In Firefox, click Tools Options. Under

the General tab, change the ‘Save files to’ setting to the directory

of your choice. In Google Chrome, click the Tools icon (it looks like

a wrench), then Options. Click the Minor Tweaks tab and change the

‘Download location’ setting there. IE users unfortunately have to hack

the Registry to make this change (a step that only power users should

consider taking).

Use Windows’ Problem Steps Recorder

2011-01-28T14:08:00.000-08:00

Use Windows’ Problem Steps Recorder.
These tips apply primarily to Windows 7

Tech support calls are a pain. If you’re having computer problems,

don’t get stuck on an endless phone call trying to explain the

difficulty. Run Windows’ Problem Steps Recorder to save a step by

step history of what you’re doing so you can share it with a friend

or tech support pro. Type PSR in the Start menu search box to find

and run the recorder. Then go through the steps that lead to your

problem; PSR will record a screenshot of each step, logging everything

you type and click. When you’re finished, click the Stop button and save

the file. E-mail the archive to someone who’s better informed for a

solution. (Note: this resource can also be used to make quick-and-dirty

tutorials.)

These tips apply primarily to Windows 7

You can shrink Windows 7’s oversize taskbar icons by right-clicking the taskbar,

choosing Properties, and selecting Use small icons. This option shrinks the size of the taskbar by half, giving you a few extra millimeters of vertical screen space.

Customize your system tray

2010-11-25T01:20:00.000-08:00

Customize your system tray.
These tips apply primarily to Windows 7

Windows 7 helpfully decreases the amount of space dedicated to

the Notification Area by putting all but the most essential

notifications within a drop-down (or, in this case, drop-up)

box. It looks nice, but you can burn lots of time with wasted

clicks as you hunt for what you need. If you want regular,

click-free access to some of these notifications, change the

default layout. It’s easy to do. Just open the tray’s spillover

window and drag the icons you want to the taskbar area. You can

rearrange icons within the added window, too.
