Windows 10 1903: Windows Defender Antivirus gets Tamper Protection feature

Microsoft released a new preview build of the upcoming first feature update of 2019 for Windows 10; the new build, the last for this year according to Microsoft, introduced a number of interesting new features and changes to the operating system.
We covered Windows Sandbox, a new sandboxing feature, earlier today already. It is integrated in all Pro and Enterprise editions of Windows 10 and can be used without installation of virtual machine images or third-party software.
Another new security related feature protects Windows Defender Antivirus from tampering.
Tamper Protection
Tamper Protection's description provides some insight on what it does:
Prevents others from tampering with important security features.
The feature itself lacks additional information, but Microsoft revealed additional tidbits on the Windows Experience blog:
Tamper Protection is a new setting from Windows Defender Antivirus, available in the Windows Security app, which when on, provides additional protections against changes to key security features, including limiting changes which are not made directly through the Windows Security app.
Tamper Protection prevents certain changes to security features to avoid misuse. Malicious applications could change security settings but with tamper protection in place, these setting changes should be blocked by Tamper Protection.
Microsoft reveals little else: we know just one scenario where changes are blocked if Tamper Protection is enabled but there are more.
How to enable or disable Tamper Protection
- Use the shortcut Windows-I to open the Settings application.
- Go to Windows Security > Virus & Threat Protection > Virus & Threat Protection Settings > Manage Settings.
- Toggle Tamper Protection on or off.
The feature was turned on in the Insider Build version of Windows 10 the feature launched in. It is likely that it will be enabled in the release version as well.
Disabling may be useful if you use third-party software such as Configure Defender which may be blocked from making changes to Windows Defender after you upgrade Windows 10 the 2019 feature update for Windows 10.
The following Registry key determines whether the feature is enabled or disabled:
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Features
- 0: Tamper Protection is disabled.
- 1: Tamper Protection is enabled.
Closing Words
The lack of information makes it difficult to judge how effective the new protective feature is. It remains to be seen how effective the new protective feature is.
Tampering Protection did not prevent any of the changes that I made using Configure Defender.
Now You: Which security solution do you use on Windows? Does it have tamper protection?


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?

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.
