Hi Nicholas. Thanks for the response.

Yes, what you mention is the standard Microsoft boilerplate, but I have
found these statements to be false in practice.

The problem is that after a service pack is installed, some of the files it
has installed can get corrupted, deleted or replaced with other versions --
versions that cause problems -- yes, I know that this is not *supposed* to
be possible under windows file protection, but in fact it DOES happen.

So, there is good reason to re-install various Windows Service Packs, and in
fact it is done all the time.

I only care about WXP SP1A because I don't have WXP SP1 available and it can
no longer be downloaded from microsoft.

Thus my question.

SP1 and SP1a "are identical in every aspect" except for the non-availability
of the Microsoft Virtual Machine in SP1a. There are no additional hotfixes
in SP1a. If you have SP1 installed, there is absolutely to reason to
attempt
to install SP1a.

John,
Believe what you wish, and of course, maintain your PC the way you wish,
but for what its worth, helpful advice, WinXP unlike the Win9x version
(Win95, 98 and ME) is base on WinNT technology, and is very protective about
its system files - most stored in SYSTEM32 folder, with a backup in
DLLCACHE, and will replace the SYSTEM32 version with DLLCACHE version when
it detects they have the incorrect version - in other words, it works and
does what it is suppose to do, but again as I said, its your choice.

John, you can get SP1 @ http://www.webtree.ca/windowsxp/ a page by Harry Ohrn. It's on the left hand side.

Huh? Sorry, but I really don't think you guys get it.

Microsoft releases new versions of core operating system files in a number
of different manners. For example, the file I am dealing with, mfc42.dll,
has a later version than the one shipped with WXP Pro SP1. Don't believe me?
Then install Windows 2000 SP4 and search %system32% for mfc42.dll. It will
be a later version.

These things aren't all in-synch, you know ... and heterogeneous
environments mean that file version mismatches are relevant -- Windows
system file protection cannot properly deal with these issues. It's a
flawed system. And that's why it's out-the-window with .NET.
