I didn't see it posted but that site offers an app that goes through the Windows Catalog and compiles a list of Windows Updates that looks very much like the old Windows Update. It works with Windows 2000 up through Vista. There is no better way to get this done. On mine it found a bunch, and like you normally have to do, at the end you reboot and run it again to get more updates. Now if there were a way to do that for all the older OSes...hahaha! Steve

I tried both versions and both have the same issue with inability to turn on RTP. I can find something else if needed. x64 didn't ship with virus protection.

Thank you Awkduck. My entire purpose is to have a fully updated Windows 98SE including all updates that came out after SP2. Not trying to resolve any specific issue but I figure the unofficial service pack resolves issues I cannot anticipate that were missed in SP2. I'm just using it on a Virtualbox VM, not a physical machine where it would be a little more difficult to start over if I messed something up. Steve Sybesma

Ah, thanks Taiga-chan. 5eraph can't be reached unfortunately...so this waits for another day. Steve

I've exhausted this much further and came to the conclusion that no matter what the facts are about being able to install Microsoft Security Essentials on Windows XP Pro x64 SP2, that Real-Time Protection cannot be turned on. That is the entire problem. It cannot be done. I even found a Real-Time Protection key in the registry into which an entry can be made to enable it, but it had no effect.

Thanks Vistapocalypse, I found with the 32-bit version of XP Pro a couple years ago what you said is the case, and my VM for that is updated as far as it can be for the engine and definitions, and I used the registry hacks to make it appear green. Question is about the XP Pro 64-bit version only, which behaves differently so far. I created a new thread with some of my last post's info, realizing nobody would probably see and be able to make use of the one I posted here. I'll check out your link. ========== UPDATE: I investigated this and came to the conclusion this doesn't seem to do anything. His work seems to be the contents of an unknown version of an MPAM-FE file which he copies to the MSE program folder but not sure what it does. More experimentation is in order. Steve

Hello Taiga-chan, The update pack was created June 2017 I believe (v2017-06_2)...but I think MS did updates until 2019 for XP Pro x86 and x64. Do you have a pack including updates to 2019 that is complete from A to Z for Windows XP Pro x64 ? (In other words the original v2017-06_2 PLUS everything to late 2019 rolled up into one download.) I'd be especially interested if anyone ever got Microsoft Security Essentials working with that. Since RyanVM.net won't accept new members, there's no way to reach 5eraph so I'm glad you took this project over. Thanks, Steve

I found a huge source for MSE definition updates tonight. Stumbled onto it as I had the idea of searching for all URLs containing the search string below once I found a complete URL for one of those 1,040 files that worked. https://web.archive.org/web/*/https://definitionupdates.microsoft.com/download/DefinitionUpdates/* Breakdown: 808 MPAM-FE.EXE captured 04/18/2013 to 02/04/2023 232 MPAM-FEX64.EXE captured 07/13/2014 to 07/24/2022 You can trust these since they're straight from Microsoft via archive.org and best part you can search the version numbers in many cases before you download them. (More than I can say than for where you can get the MSE installers from...haven't found an MS archived source for those yet.) Some of these may be duplicates (obviously there weren't really 1,040 unique versions), but still. Now... I found two versions of 64-bit MSE that will successfully install under XP Pro x64, but curiously the newer version (4.5.216.0) has to be installed AFTER the older one (4.4.304.0) and that seems to be the very last installable version (that doesn't throw up any error). Source for older MSE versions (there's lots on this page both 64-bit and 32-bit): https://www.filehorse.com/download-security-essentials/ That older version is the same one that also installs under XP Pro x86, except 32-bit. The problem is all the definition updates I tried up until this find did not work. I struggled for hours a couple days ago. It's possible I didn't try enough as before this find I only had a couple to work with. Steve

Definition Updates for MSE anyone? So far this is the largest cache of MPAM-FE and MPAM-FEX64 I've ever found (exactly 1,040 of them - TONS!). Breakdown: 808 MPAM-FE.EXE captured 04/18/2013 to 02/04/2023 232 MPAM-FEX64.EXE captured 07/13/2014 to 07/24/2022 Stumbled onto it because I had the idea of searching for all URLs containing the search string below once I found a complete URL for one of those 1,040 files that worked. https://web.archive.org/web/*/https://definitionupdates.microsoft.com/download/DefinitionUpdates/* You can trust these since they're straight from Microsoft via archive.org and best part you can search the version numbers in many cases before you download them. Some of these may be duplicates (obviously there weren't really 1,040 unique versions), but still. Now you can update MSE using the latest possible definitions for your Windows XP 32-bit/Vista/7 VMs. Keep in mind Microsoft set a definition version limit on these for each OS version. Same idea applies to the MSE program version as well. So the latest available can't be used with XP for instance. You'll have to figure out where that cuts off but that info may be posted elsewhere. It will be evident that it works if MSE acknowledges the definition version you just installed...if it's newer than it can accept, there will be no change even though there may not be any visible error. (Too bad MSE doesn't work with XP Pro x64...oh, well. I struggled many hours with that before finding this huge resource. If anyone ever did get it working, please provide complete details.) Enjoy!

I remember many years ago that project was based on this website and I was a member back then but I guess my membership lapsed and was deleted. I found this here: http://www.techtalk.cc/viewtopic.php?f=1047&t=65 Steve

This OS has always presented a challenge to me because some apps won't install on it that will install on Windows XP Pro x32. There seems to be a much bigger divide on this OS between its 32-bit 'sibling' than most other versions of Windows. May have had something to do with the code base of x64 being based on Server 2003 while XP 32-bit was not. Kind of a shame because this OS had a lot of potential. Later OSes like Vista and 7 seemed to close that compatibility gap much more. So the key is finding the app versions that makes it happy, whether that has to be a 64-bit app or not. I would like to develop my XP x64 Virtualbox VM so that it's just as useful as my XP Pro 32-bit VM. Steve

There is a slipstreamed Windows XP Pro x64 ISO here that's almost 900MB in size compared to the stock Microsoft one I had which was about 350MB less. Supposedly has all updates to April 2019. https://archive.org/details/xpx64_slip This is a good starting place to go from in case a few updates were missed. I'm using it in a Virtualbox VM and it's a very clean distribution...no junk was added to it. Now if there were just a community of interest in this OS to share what apps work and don't work. It's a very finicky OS that needs some help to open up its usefulness. I found out Microsoft Security Essentials absolutely can't be made to work on it...even though a couple older versions can be installed. Steve
