Recently the Yahoo Messenger 9 was released, and at once it was clear that all add removing techniques which were used in the older builds, like version 8.x (early builds) became obsolete.
The new versions were more resistant to patching. Therefore they needed some more fiddling around and finally there is a patch which can be used by all to remove the annoying ads from this messenger, like the previous technique this is also a registry hack but it has more to do than registry hack, it makes the yahoo ads cache read only so new ads will not load after the patching process.
Please keep in mind that this has some issues with FAT 32 disks, as this disables features like Chat rooms and the plugin manager, therefore use this in Vista OS or XP in a NTFS partition.
The file provided here edits most of the registry values for the yahoo ads, which can be found at HKEY_CURRENT_USER\Software\ Yahoo\pager\YUrl this hack replaces the data with an asterisk.
Messenger Ad
Webcam Upload Ad
Webcam Viewer Ad
Webcam Viewer Ad Big
Webcam Viewer Ad Medium
Change Room Banner
Conf Adurl
Chat Adurl
Plus It also clears the ads cache found in C:\Program Files\Yahoo!\Messenger\Cache\urls.xml and makes it read-only (this is the sore purpose why NTFS is required).
Whenever you upgrade to newer builds, please follow these steps again

Heads Up!!!
Yahoo! is changing a couple things…
First, if you have more than one Yahoo! account using the
same primary e-mail address, you may lose the account.
This is a gradual change; I have seen no official announcement.
But, I wanted to make a new Yahoo! ID and in the process,
I was informed that any other account that had the same
“primary” e-mail addess would become inaccessible.
Second, I noticed that, by the end of the year, Yahoo!
intends to do away with geocities free hosted sites.
So, if you have any geocities sites bookmarked for great
info or downloads, best get crackin and get what you want.

@dedndave:
this sucks I have accounts like that
of course, i do not know what yahoo intends to do
i am viewing this as “writing on the wall”, though
i have a few yahoo accounts that are critical
for each of those, i am creating hotmail accounts as primaries
i also have several yahoo accounts that i could stand to lose
i am going to take my chances with those, as i don’t want to
exhaust hotmail resources, as well as my own time
version 10.0.0.331 Beta patched:

Downloaded and installed and worked great on ads on the messenger list. I am, however, still having the annoying ads in each messenger screen with an individual. The ones that are words beneath the area where you type. I am forever clicking it accidentally when going from different screens. Then it opens an internet page. Anything to get rid of those?
Hi, to anyone who is still visiting here. I’ve been looking around for a Win7 X64 Y!M 9 or 10 patch for a while now. I have read all of the previous posts here, and it seems that there was some work being done on it about 6 or so months ago, but I guess the discussion went elsewhere, or it just lost it’s steam. Anyway, can anyone tell me if anyone has successfully written the patch for X64 Y! messenger 9 or 10? Any version of 9 or 10 would be fine with me I guess. I have tried, unsuccessfully, to use a couple different versions of Y!M 9 with their corresponding patches (most written by dedndave), and they do work on my xp machines, but i have a couple Win7 X64 machines too, so of course, they do not work there. I would be happy using pretty much any version of YM that works, as long as I can patch it to remove the ads in Win 7 X64!!!!
