Is this ok to install? I have never seen an update which says "Once you have installed this item, it cannot be removed."

I installed it yesterday. Hmmmmmm.

From Microsoft, an explanation why it is needed:

When an application uses MSXML to process XHTML, redundant retrieval requests for well-known DTD files from the W3C Web server cause XHTML parsing to fail on a Windows-based computer

So if you don’t mind this potential problem, then don’t install it.

I am sure it is, haven’t read anything out there to say otherwise. Now I am sure you will still be able to read xml documents if you don’t install it.

Once you have installed this item, it cannot be removed.

I seem to remember this line scrolling across the bottom of my TV screen during Obama's inauguration.

Actually, a LOT of MS patches can’t be uninstalled without uninstalling subordinate patches or screwing up a COM descriptor or corrupting a DLL.

I installed the patch you mentioned on my machines, and they’re running fine. It sounds like a patch to help prevent DOS attacks on sites with valid DTDs.

Install this update to prevent applications from sending too many HTTP requests while a well-known Document Type Definition (DTD) is included. After you install this item, you may have to restart your computer. Once you have installed this item, it cannot be removed.

I think I installed it yesterday, since I have auto update.

Is it to prevent your computer from being used as part of a botnet or something?

There is a solution to all your windows problems: Ubuntu Linux

There's a learning curve, but Ubuntu is pretty awesome. If I could get my windoze games to run under Linux, I'd dump M$ windoze for good.

“Once you have installed this item, it cannot be removed.”

This is not uncommon with MS patches.
