I have flagged this issue internally and hope for a Technician to come in here soon.
Meanwhile you may want to take a look at slipstreaming SP3 into your existing system disk, so you will always have a disk that can be used to repair the system.
Of course it would then need updating to the most current updates.
Similar procedures exist for Vista and Windows 7 too.
They are very similar except they use different tools, all free.
Two caveats: never interrupt a service pack installation and cleanup, ever. That could be one reason why things aren't going as they should. The same goes for any kind of Windows update really.
Always disable antivirus protection during a service pack installation, and any other process that may autorun during that period, even email. Tutorial here: https://community.mcafee.com/thread/2007
other than that all I can suggest is reboot once more and if no improvement contact Technical Support Chat available via Useful Links at the top of this page.
Same problem here. It's actually quite maddening. Hopefully, you'll know something more early next week
I'm hoping someone for the Tech Support side will answer my flag, but I can't promise anything. Meanwhile you could try contacting them via the link at the top of this page under Useful Links.
I turn off my (Windows XP) screensaver when doing something where the computer can work for a long time unattended, such as a full virus scan. When I tried to reactivate the screensaver via the Display settings I found it hung and was difficult to get working again. I looked for .scr screensaver files and found I had several copies of these. One set is in C:\i386 dated 4/8/2001 (presumably the ones fromwhen I bought the computer), another is in C:\Windows\System32 dated 14/4/2008 (these are probably the ones installed by the SP3 service pack). I am not sure which of these Windows uses when selected from the display settings but probably the latter. I also have other copies of the screensaver files in folders which suggest these should have been deleted in the SP3 cleaning up process which I had to abort.
Whenever I tried to activate the screensaver again or when I tried running this by double clicking a .scr file in any of the locations, the unrecognised files error would occur again at some time after this.
As I test I turned my screensaver off and did not get the unrecognised file error through several restarts (I had to go out several times and did not want to leave my computer on) and for almost 24 hours. The error message appeared again when Windows Defender did a scheduled daily scan. Just using the computer with the screensaver turned off seems to allow normal working otherwise.
Maybe this information will be of generally help and also assist in tracking down the underlying cause.
As I said best to open a case with Technical Support Online Chat linked via Useful Links at the top of this page - reason being no technicians have been seen on the board all weekend.
They can escalate the case as and when necessary.
It doesn't happen all the time and whatever was changed does not seem to be effecting my computer or its performance. It would be nice if Windows XP would not only warn you of the files being changed but tell you which ones they were.
Well, if it occurs too often I would still have Tech Support take a look. It's your choice of course.

Just a comment about SP3. The first time I ran the SP3 update (when it was first available) I left the cleaning up process running for about 4 hours! I used the task mananger in desperaration in order to stop it and everything seemed to be OK. Searching on the internet I then found that this appeared to be a common problem and that many had this. Using the task manager to stop the process during cleanup was the ONLY way to exit the SP3 update for many. I have had no problems with Windows since until this new one now.

By chance I have found that with my system I do not get this error if I leave my (Windows XP) screensaver turned off (i.e. I am not now using a screensaver) EXCEPT everytime Windows Defender does a scan. Likewise my computer is otherwise performing correctly with all the programs I have used since.
