Recovering Deleted Desktop Icons
There’s no other major item most of us own that is as confusing, unpredictable and unreliable as our personal computers. Everybody has questions about them, and we aim to help.
Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about recovering deleted icons, clearing search histories and the difference between laptop processors.
If you have a question, send it to me at email@example.com, and I may select it to be answered here in Mossberg’s Mailbox.
I accidentally deleted from my Windows XP desktop the icon for a program I use often. I know that this doesn’t mean I have deleted the program. But how do I get its icon back on the desktop?
There are multiple ways to do it, but here are a couple. You can click on the Start Button, then on All Programs, then locate the entry for the program, and just drag that entry onto your desktop. Or, you can locate the program file itself (it’s typically in a subfolder of the Program Files folder), select the file, click the right mouse button and then click on “Send To.” From the next menu that appears, select “Desktop (create shortcut).”
In the Firefox Web browser, how do I erase all traces of my browsing activity, so another user of the same computer can’t see what I’ve been doing online?
Go to the Tools menu, and select “Clear Private Data…”. This will bring up a list of traces that can be expunged. You just check off the ones you want obliterated, and then click on the button at the bottom labeled “Clear Private Data Now.”
To be absolutely safe, you can check off the entire list, but, generally speaking, clearing the browser history, download history, cookies and cache should hide your tracks from a casual user.
Be aware that there’s a downside to this. After clearing out this stuff, your Web surfing could slow down a little, because you won’t have any cached pages for the browser to use to speed up the loading of sites you’ve visited in the past. Also, by purging all cookies, you will lose the automatic log-ins and saved preferences, from some sites.
I am shopping for a laptop, and am confused by some of the processor choices. Specifically, what is the difference between Intel’s new Core Duo chip and the Core Solo chip?
Both are new designs, which combine power with greater efficiency. They run cooler than older processors, thus allowing for thinner laptops, fewer fans, and, in some cases, better battery life. But the Core Solo is, like most past processors, a single digital brain. The Core Duo packs two brains — two “cores,” each the equivalent of a single processor — onto one chip. This potentially offers greater speed in performing tasks on the computer, especially when you are running several programs at once, and especially if one or more of the programs is demanding.
Bear in mind, however, that to get the most out of the dual-core design, your software should know how to use the twin cores. Not all software does, though this should improve over time, as software is revised to better use the new chips. Also, the overall performance of a computer depends on many factors beyond the processor. These include how much memory you have, the power of the video subsystem and the speed of your Internet connection.
