Fix for the System Service Exception of KB4490481
Microsoft released the second cumulative update KB4490481 for Windows 10 version 1809 on April 3, 2019 to address a large number of issues and make some changes to the system.
I ran into a brick wall each time I tried to install the update on a Windows 10 Pro machine. Windows Update would install the update just fine but would throw a blue screen error System Service Exception on the first boot of the system after update installation.
I had to use System Restore to restore the system state, other troubleshooting options, e.g. startup repair, did not work at that time.
Microsoft has not acknowledged the issue officially, it is not listed as a known issue on the support page of KB4490481.
Fixing System Service Exception
A user on the My Digital Life forum published a solution for the issue yesterday. The user suggested to remove certain entries in the Windows Registry to fix the issue and get KB4490481 to install on machines that threw bluescreens before.
Note: The process requires editing the Registry. More precisely, removing entries from the Registry. I suggest you back up the Registry, or at least the keys that you are about to delete, before you proceed. Creation of a System Restore point is also an option.
The process
- Tap on the Windows-key, type regedit.exe, and load the Registry Editor.
- Confirm the UAC prompt that Windows displays.
- Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink
- Locate the following entries there and delete them with a right-click and selecting "delete" from the context menu:
- MS PGothic MC
- Segoe Media Center
- Segoe Media Center Light
- Segoe Media Center Semibold
Install the KB4490481 update again afterward. The update should go through this time without Windows 10 throwing a blue screen on the first full start of the system after update installation.
Closing Words
It is unclear why these entries would be the cause for a blue screen error after update installation. The four fonts appear to be linked to Media Center which Microsoft removed from Windows 10 (see our list of Media Center alternatives).
It feels strange that something as mundane as font entries in the Registry would cause the entire system to throw a bluescreen error.
Anyway, if you ran into the same System Service Exception error while installing KB4490481 you may want to try removing the entries in the Registry to see if it fixed the issue on your end.
What mental age of reader are you targeting with the first sentence? 10?
Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.
If your paymaster Microsoft permits it, of course.
5. Rufus
6. Ventoy
PS. I hate reading these “SEO optimized” articles.
I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.
bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.
ps…. time travelling?

This happens when you schedule a post in WordPress and update it before setting the publication date.
Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.
I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:
1) Too young to remember a time before W10 and W11 (doesn’t know better)
2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)
3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””
4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows
5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss
Obviously that doesn’t cover everyone, there’s also the category that:
6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now
Have I missed any group off this list?
You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.
Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.
Microsoft has removed KB5029351 update
only from windows update though
KB5029351 is still available from the ms update catalog site
1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.
2. I have installed it in a 11 years old computer, and no problems at all.
3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.
This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.
Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.
Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.
Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.
motherboard maker MSI has recently released a statement regarding the “unsupported processor” blue screen error for their boards using Intel 600/700 series chipsets & to avoid the KB5029351 Win11 update:

While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.
My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
