From a forum entry on Bangkok Images:

Hello, can anyone help with this question.

I use PhotoCAL to calibrate my system and have to make sure that adobe gama is not in the startup folder.

In Win XP installing programs like Adobe Photoshop CS2 Adobe Gama is installed in the startup folder.

I have Win 7 on my Laptop and I cannot find any folders that show a similar folder, so is adobe gama still loaded by default.



Hi Charles -

As you know, Adobe Gamma was a 'very rough' method of adjusting your screen and colors from years past.  When using a color profile software/device you'll for sure want Adobe Gamma disabled or it will conflict with your color profiling device and create all kinds of havoc.

I think.. but I'm not sure.. that because Windows XP doesn't have a color management control applet, or at least it didn't until Windows provided an optional color management applet somewhere between SP2 and SP3.. that Adobe automatically installs their gamma profiler on XP.  Vista and Win7 both have built in color management applets.. and while there used to be some issues with Vista's color applet working correctly.. those issues have been long solved with current video card driver updates along with Window's Vista service pack (SP) updates.  Win7 had absolutely no issued with it's color management unless you're trying to color profile two monitors and then it 'can' get a bit weird and is a topic unto itself.

For these reasons I don't think Adobe installs it's Gamma profilers on Vista or Windows7 systems.  At least nothing I've ever noticed when setting up many such computers.

However, there are two places to check.  One is your startup folder.  Make sure only what you need is here.

Another is your msconfig.sys file.  You can type this in your run command line in your Win7 startup menu and it will come right up.  Choose the "startup" tab and uncheck anything that says "Adobe Gamma" if you can find something (you won't) and then take this time to look at all those programs starting and running automatically and ask yourself if you really need them.  If in doubt if you need one of those programs then Google it and you'll find multiple (hundreds) of references talking about that file and if it's safe to disable it.  I recommend only running what you absolutely need in your startup folder.  On systems with limited CPU power or limited ram, these adjustments can give you a huge performance gain.  Even with a high power system you can get a huge performance gain.. for sure the way to manage your system.. as little loaded in resident memory as possible.

I hope this helps.
