Q. I do not own a scanner - mainly due to space,
but I do have a couple of digital cameras, which I have used to take copies of
important documents. This all works very well, but I do miss the ability to do
Optical Character Recognition on these images. Is there a free OCR program out
there that could be used to convert these images to text?
Andrew Peaty, via email
A. There is and I have been very
impressed with a freeware program called TopOCR,
which is designed for use with digital cameras, camera phones and other imaging
devices, as well as scanners. I have got very good results from photographs,
though it is important to tweak the image first, to increase the contrast, and
like all OCR software it won’t reading fancy fonts or handwriting. Scanned data
can be exported as a plain or rich text format (.txt/.rtf), PDF or HTML files.
Q. I have an
IBM ThinkPad laptop running Windows XP. I've recently started using USB memory
sticks, however, when I plug one of them in, a balloon appears saying: ‘This
device can run faster…’. I follow the instructions but, being a complete bozo
as regards USB, I can't do much about it!
Chas Hobson, via email
A. This
message basically says if you update the drivers on your PC USB2.0 devices
should run a little quicker. This is a fairly straightforward job and you
should find the right driver for your machine and some instructions on the IBM
support site. However, the improvements are likely to be fairly small, unless
you are moving lots of large files to and from USB modules or you plan on using
peripherals that benefit from USB 2.0 connectivity, such as external hard
drives, video input/output devices and high-end scanners and printers.
If you just want to keep things simple and make
the message go away then all you have to do is open Device Manager (Winkey
+Break > Hardware > Device Manager). Double-click on Universal Serial Bus
Controllers to expand the branch, right-click on each 'USB Host Controller'
entry in turn, select the Advanced tab and deselect 'Don't tell me about US
Errors'.
Q.
I recently had to take my PC in for repair. When I got it back, the technician
said that he noticed that I was running a commercial Registry cleaner program
and warned me to stop using it immediately, because it could corrupt the
Registry. I asked him if he could recommend a suitable cleaner, but he replied
that they were all dangerous. Is this really true, because I have read a number
of recommendations for such programs in computer magazines?

I think the tech is being a tad alarmist. A cynic might even say that people
trying to fix their own PCs could put him out of business. Nevertheless, there
is some validity in his advice. The Windows Registry is a vitally important
collection of system files and small changes can have far-reaching effects, up
to an including making a PC inoperable. There are also a number of rogue
Registry cleaners that generate false positives in an attempt to scare you into
buy other probably equally useless products or services, so you need to be on
your guard.
As regular readers will
know I have been recommending RegSeeker for
several years and in addition to being completely free, it also does a pretty
good job of clearing out the clutter, hopefully making your PC run a little
smoother. The other major plus point is that it automatically backs up the
Registry, before making any changes, so in the unlikely event that something
does go wrong, it can be easily fixed.
Q.
There is no sound when using the Caps Lock key, even though I've checked the
'Use Toggle Keys' (Start > Control Panel > Accessibility Options -
Keyboard tab). I would be grateful for further advice
Peter Gunn, via email
A. The bleep, and I have to say
it’s not very loud, is piped through the PC’s small internal speaker. However,
it’s not unknown for manufacturers and system builders to forget to connect it,
or leave it out altogether, which may be what has happened in your case. You
could check the connections to the speaker but it’s much easier to install a
little freeware utility, like First Cap,
which generates an audible alert for the Caps and Num Lock keys, and this will
be heard through your PC’s main speakers.
Q. When I copy photos from my
camera to the computer they are transferred in the correct order, that is to
say, the order in which they were taken. However, I have also been using a card
reader and this transfers the pictures in a random sequence. I have tried two different card readers and
they both do the same. Presumably, therefore, it is my PC, which is causing
this. Is there something that I have to
do or can do to get the card reader to put the photos on in sequential order?
Ken Brown, Newcastle upon Tyne, NE21 6HS

This kind of query crops up on a fairly regular basis so here’s a quick recap
on the way Windows displays files. When you open a folder in Computer, Windows
Explorer or My Computer the files are usually ordered alphabetically or
numerically, but there are many other ways. They could be in chronological
order, or according to file type, the size of the file and so on.
To select the order or
criteria all you have to do is click on the label at the top of the column you
are interested in. It’s a ‘toggle’ action, so if you click again it will
reverse the order. For example, if you click the Name column header the files
will be ordered A to Z, click again and it switches to Z to A. All of the
column labels work this way, and you can add extra ones, or remove those you
don’t need by right-clicking on the label bar.
