Critical font parsing issue in Windows revealed (fix inside)

Microsoft published an advisory yesterday concerning a recently detected font parsing issue that affects all supported versions of the company's Windows operating system (including Windows 7).
The issue is rated critical, the highest severity rating. Microsoft notes that it is aware of limited targeted attacks and that it is working on a fix to close the vulnerability.
The remote code vulnerability is found in the Adobe Type Manager Library and attackers have multiple options to exploit the issue including convincing users to open a specially crafted document or viewing the document in the preview pane of File Explorer / Windows Explorer.
Two remote code execution vulnerabilities exist in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi-master font - Adobe Type 1 PostScript format.
A workaround has been published by Microsoft that prevents attacks targeting Windows Explorer / File Explorer. Microsoft notes that the workaround does not "prevent a local, authentication user from running a specially crafted program to exploit the vulnerability".
The workaround:
For Windows 7, Windows 8.1 and Windows Server 2008 R2, 2012 and 2012 R2:
- Open a Windows Explorer instance and select Organize > Layout.
- Disable the Details pane and Preview pane options (if they are enabled. You should notice that the panes are not displayed when disabled)
- Select Organize > Folder and search options.
- Switch to the View tab.
- Under Advanced Settings, check "Always show icons, never thumbnails".
- Close all Windows Explorer instances.
For Windows 10, Windows Server 2016 and 2019:
- Open File Explorer and switch to the View tab when it opens.
- Clear the Details and Preview pane so that these are not displayed in File Explorer anymore (if they were displayed previously).
- Select File > Change folder and search options.
- Check Always show icons, never thumbnails in Advanced Settings.
- Close all File Explorer instances so that the changes can take effect.
The changes can be undone once the fix landed in Windows. Just repeat the steps outlined above but instead of clearing or checking the options, you'd do the opposite.
For systems on which the WebClient service is used, Microsoft recommends disabling the service for the time being as it blocks "the most likely remote attack vector through the Web Distributed Authoring and Versioning (WebDAV) client service".
Disabling the service will result in WebDAV requests not being transmitted. Also, any service that depends on the WebClient service will not start.
Here is how that is done:
- Use Windows-R to bring up a Run box.
- Type services.msc and click OK to open the Services Management window.
- Locate WebClient in the Services listing, right-click on it and select Properties.
- Switch the Startup type to Disabled.
- If WebClient is running, select Stop.
- Click ok and close the Services management interface.
Administrators who manage Windows 10 version 1703 and earlier systems, including Windows 8.1 and 7, may also disable ATMFD using the Registry.
Here is the script that you need to run:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows]
"DisableATMFD"=dword:00000001
Non-ESU Windows 7 systems won't receive the security update according to Microsoft.


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.

I try to disable the Diagnostics Tracking Service (Connected Devices Platform User Services) but it wont let me disable it, any help will be greatly appreciated.
Tank you for your help
