Save downloads to a different directory

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

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.)

Give yourself more screen real estate in Windows 7’s.
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.
