Has anyone noticed this WindowsWcpOtherFailure3 error in Event Viewer?

This is one oddity I don't have yet.

This didn't take long, issues with the new People app in Widgets

Here 2026-02 Security Update (KB5077241) (26200.7918) Override 14 - Enable All Features.reg

This particular override messes up my taskbar - many systray icons don't show after logging in up until I restart windows explorer, but still some still don't show. So I have commented it out. This has been going on for several insider releases.

# New Taskbar Animation. ViVetool ID: 41356296 (CFR RKey: 276172940)
#[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\FeatureManagement\Overrides\14\276172940]
#"EnabledState"=dword:00000002
#"EnabledStateOptions"=dword:00000000

All the rest work fine as far as I can tell. The new network speed test in the taskbar is pretty useless. All it does is open a speed test in your browser. But surprise - it opens it in your default browser and not Edge (unless your default is Edge).

Upgraded without issue. DISM/SFC were clean.

I have the same problem with people app (in 7840), but I don't have Today's Moment app (Maybe it not available in Israel).

Still no fix for the white flashing and the black flashing after this update to 26200.7918.

In the early UUP Insider Preview builds, I remember that 25H2 contained many options, such as adding a new taskbar. In later builds, and in the current one, to activate some of these features that were removed, I had to install Explorer Patcher and Stardock Start11. With the File Explorer - Windows 10 Ribbon option, I don't see the flickering, neither black nor white. This bug, like the language issue in Windows security settings, is one of the problems they haven't been able to fix yet.

Mister @uncyler825 I lost the new privacy and security settings menu with this update. Do you happen to know the new vivetool id or did you lose it as well? Your new registry file was applied and it's still gone. No big deal it was gone before applying that they must of changed the vivetool id for it in this update as it was working prior.

The People widget hasn't worked for me since it was first available.
"Widget can't be added at this time" error

It could have been pulled for now by MS.

26200.~~7918~~ 7921...installed... Apparently, they decided to skip the one they pulled.

I can see no difference in this build than 26200.7840. I may go back to it.

Would help to know what the new Privacy & Security page looks like.
Do you have a screenshot of the new page?
I don't see any difference with or without that ID 57118881 enabled.

bazookaeastern · Feb 18, 2026

The increased space occupied by the new update KB5077241 26200.7918 is over 8GB, which seems excessive unless it involves a major system overhaul.

I have some portable applications infected with something that the system detected and blocked from execution after update KB5074105, but did nothing else. With KB5077241 26200.7918, the antivirus manages to bypass it and detect it. You can create an exception three times; on the third attempt, it deletes the file and blocks its execution after recovery. If Microsoft's goal is to improve the detection of infected executables, they're succeeding brilliantly. None of the executables and scripts it's detecting as infected were previously flagged as suspicious.

Now I feel as if all this time I've had the front door wide open

If there are any notable differences between versions 26200.7840 and 26200.7918, for now I only know that when an infected file is detected, with 26200.7840 Windows Defender will just stand by and do nothing, or be unsure what to do. With 26200.7918, Windows security will trigger, and this will then trigger your installed antivirus. With version 7899, it either doesn't react at all or gets stuck halfway.

I have several infected files that I use to test the security and antivirus, and this new 26200.7918 system is very effective and reliable because it doesn't suffer from paranoia.
