EnvUpdate() not working for me....

[Fossil Rock]

Am I implementing it wrong or missing something ?

If I read it correctly I believe its for the environment variables as the help explains.

If you change the %path% you would update it by executing EnvUpdate() so you wouldn't have to log off and back on.

For reg keys seems like I seen something might work somewhere on the forum, but for the life of me I can't remember what was at this time.

I noticed that when I turn the font smoothing on and off with the Display Properties it stores different data than the script. I don't know if they are considered to be the same or not.

The top pair are from turning the font smoothing on to off from the Display Properties.

The bottom pair are from turning the font smoothing on to off from the script.

The help file states the TYPE is optional, but when I leave it blank [ RegWrite("HKEY_CURRENT_USER\Control Panel\Desktop", "FontSmoothing", "", 0) ] I get ERROR: RegWrite() called with illegal argument 3: ""

Do you know of any method to force an update like the 'Apply' button in the Display Properties ?

Might be something to look at http://www.autoitscript.com/forum/index.ph...st&p=156286
