SpeedswitchXP is a small applet that sits in the system tray and
allows dynamic switching of the frequencies of mobile Intel and
mobile AMD CPUs under Windows XP. During the development of
Windows XP, Microsoft decided to integrate dynamic frequency
switching into the operating system itself. On a default Windows
XP installation, the power schemes in the power settings of the
system panel control the frequencies of the processor. On Windows
2000 and previous operating systems, it was possible to manually
control the CPU frequencies with a SpeedStep applet provided by
Intel, but this is not possible anymore under Windows XP. It is
not very good documented what the different Windows XP power
schemes do and it is impossible to fully adjust the schemes as
the important settings are not accessible through the control
panel.


SpeedswitchXP tries to fill this gap in that it provides access
to ALL power scheme settings. This small applet is similar in
functionality to the native Intel SpeedStep applet for Windows
9x/ME and Windows 2000 but with a few more options.


Basically all it does is creating a power scheme under the power
settings in the system panel and making this the default power
scheme for Windows XP. When this is done, you can control all
settings of this new scheme through the applet.

Since this program is using Windows XP's internal processor
performance control functions, it should work on all notebooks
that feature dynamic speed switching. So far, it has been
successfully tested on notebooks with the following mobile CPUs:

CPU type Tested notebooks
Mobile Pentium III-M Dell Inspiron 4100/8100,
Dell Latitude C610/C810
Mobile Pentium 4-M Dell Inspiron 8200/8500,
Dell Latitude C840
Mobile Pentium 4 Dell Inspiron 5150
Mobile Pentium M /Centrino IBM Thinkpad T40/T40p,
Dell Latitude D800
Mobile AMD Athlon XP Peacock Freeliner XP,
Fujitsu-Siemens Amilo A x600

I used to like it very much, until I decided not to work with admin
rights any longer. Since I removed my user account from the admin
group, the Autostart doesn't work anymore. Any hints?

I even tried with "runas /user:Administrator d:\programme..." but no
luck.

I havent tried this, on my way out now...but you might try
to open regedit and find

<HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies>,

right click it and assign permissions from there. As said, not tested,
so don't know if there is a more global "no policy editing rights" for
limited users (not poweruser or admin) that overruns this,
or if there are other power-related reg-keys that need tweaking.

Thank you so much, Bjorn!

I didn't knew I could set permissions inside regedit, so I never tried
this approach. It works now as it should.
