41. Improved Calculator
Windows 7 features an improved calculator that
can do unit conversion, date calculation, gas
mileage, lease, and mortgage. Also you can choose
between Standard, Scientific, Programmer, and
Statistic calculator.
42. Open A Folder In A New Process
Windows 7 opens all folders in the same process in
order to save resources, but this means if one
folder crashes, they all crash. So if you feel like
that’s a risk you don’t have to take, then you have
to open them all in their own processes.
To do this, hold down Shift button, right-click the
drive and “Open in New Process”. Now you will be
safe.
43. Problem Step Recorder
The Problem Step Recorder is a great tool that can
be used in many circumstances. You can turn it on
by pressing the Windows Key, then typing
“PSR.exe” and click Record. Now it will record all
your moves and save them as a HTML document
that you can view or write descriptions to it. This
can help you with troubleshooting or when writing
a guidance or tutorial.
44. Free Codecs Pack
Unfortunately, Windows Media Player still isn’t able
to play many audio and video files, so you will still
need some codecs. But with the free codecs pack
you can download here you shouldn’t have any
problems.
45. Start Windows Explorer From My Computer
Windows Explorer opens in the Libraries directory
by default. Most of us are used to see the My
Computer page instead.
To change it to My Computer, press the Windows
Key, then type “explorer”, select Properties and in
the Shortcut tab type “%SystemRoot%\e
xplorer.exe /root,::{20D04FE0-3AEA-1069-A2D8
-08002B30309D}”. Now you have to right-click the
Explorer icon in the Taskbar and hit “Unpin this
program from the taskbar” and then drag it back
from the Start Menu.
46. Clear The Desktop
If there are too many windows on the desktop, you
can clear it by shaking a window from left to right
and all others will minimize. To restore the other
windows you have to shake the active one again.
47. Use Gadgets With UAC Turned Off
Maybe you noticed that once you turn off UAC you
can’t use the gadgets anymore, as a security
measure. But if you want to risk using them, there
a simple way to do it, even with UAC turned off.
Press the Windows Key, type ‘regedit’, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft
\Windows\CurrentVersion\Sidebar\Settings and
create a DWORD value named AllowElevatedPr
ocess and set its value to 1. Now you should be
able to use your gadgets. If not, then reboot your
PC and you should be done.
48. Fix The Media Player & Media Center MP3 Bug
If you have the final version of Windows 7, then go
ahead and skip this one, since it applies only to
Beta and RC versions.
Both Windows Media Player and Windows Media
Center come with a bug that can damage your
MP3s by filling missing metadata automatically on
imported MP3 files. This can cut a few seconds
from the beginning of the tracks and can prove
really disturbing. This problem was fixed by
Microsoft using the fix that you can download here.
49. Search Everything In Your Computer
Windows 7 offers the possibility to search all file
types, including unknown ones and this could help
you in some cases.
Though it is not recommended, because it’s much
slower than normal search, you can give it a try by
doing the following: Launch Windows Explorer, go
to Tools -> Folder Options -> View and check “Try
to search the content of unknown file types”. If you
don’t need it anymore, don’t forget to clear it for
an increase in speed.
50. Mouse Gestures
Windows 7 has not only brought gestures for those
who use touchscreen devices, but for mouse users
too. So, instead of right-clicking a Taskbar icon to
access the jump list, you can hold left-click and
drag upwards to smoothly call it up. In addition,
clicking and dragging down the address bar in
Internet Explorer will open the browsing history.
There might be more gestures yet not discovered.
