Windows Defender Notifications Not Working — Even After Clean Installs, BIOS Reset & Full Repairs
Hi everyone, I’m facing a strange and persistent issue with Windows Defender notifications, and I’m hoping someone here may have encountered something similar. During routine system maintenance, I noticed that Windows Defender has completely stopped showing notifications — no scan completion alerts, no threat‑found pop‑ups, nothing at all. Troubleshooting I’ve Already Done To rule out corruption, configuration issues, or hardware‑related causes, I’ve carried out extensive testing across multiple clean installations: Reinstalled Windows using the Media Creation Tool → still no Defender notifications Reinstalled Windows again using Rufus → same result Reset BIOS / cleared CMOS Installed an older Windows 11 build (offline, before updates) → still no notifications Deleted all partitions on every reinstall (full clean install) Verified all Windows Defender notification settings, including Enhanced Notifications Checked Windows notification settings to ensure Windows Security is allowed Ran SFC Performed DISM /Online /Cleanup-Image /RestoreHealth Confirmed no registry or Group Policy entries suppressing notifications Reinstalled Windows Defender components Scanned with third‑party tools and Microsoft MRT — no issues found Ensured Windows Push Notification System Service is running Despite all of this, Defender notifications never appear on any fresh installation. Microsoft Support I opened a support ticket with Microsoft. One engineer performed an in‑place repair install Another advised me to post the issue here for deeper investigation Ticket reference: 710148747 Additional Technical Findings 1. Notifications are not being suppressed No GPOs applied No Intune configuration profiles No registry entries modifying notification behaviour Local notification settings fully enabled Defender notifications fully enabled It’s not a profile corruption It’s not a user hive issue It’s not a local DB issue It’s OS‑level 2. Windows Notification Platform (WNP) appears to be the root cause Across multiple clean installs: ShellExperienceHost exists on disk. Focus Assist toggle produces no toast (not sure it does) other apps like mail, Logitech, steam can toast notification, i don't see defender toasting any scan notification. WNP is partially working Defender is partially registering The scan‑completion channel is failing specifically This behaviour is consistent and reproducible. 3. Defender functionality validated using EICAR I manually created the EICAR test file and ran a scan: Defender detects and removes the file correctly Detection appears in Protection History A threat notification appears Scan completion notifications do NOT appear This confirms: Defender itself is functioning The notification delivery layer (WNP) is not working question at MS QA- https://learn.microsoft.com/en-us/answers/questions/5864084/windows-defender-notifications-not-working-even-af
To the security / permission developers
Please refrain from working on any and all software for the rest of your lives. Get a job shoveling dirt. There is no reason as a single user with admin rights, should be denied from accessing / modifying any files or folder on my PC without having to jump through a thousand hoops. Even after granting ownership, I'm still getting screwed. And by the countless forums I see about other people experiencing the same issue, there's still no light at the end of the tunnel. So, for the love of god, just stop what you are doing before it gets worse.No 'trust this computer' prompt showing up on my iPad

Hi, The Microsoft Edge browser has been consuming a lot of CPU and RAM on my Windows 11 computer lately, even when only a few tabs are open. It's starting to slow things down, especially during multitasking, and the built-in browser keeps running in the background. Tried removing it through windows 11 settings and control panel, but the uninstall option is greyed out for system app like edge. Is there a reliable way to completely uninstall microsoft edge browser from Windows 11, or at least stop it from running and using resources?
Personal computer used at work sign-in options
I got a new personal windows 11 laptop I use at work. My boss had me sign into my company Microsoft account to add windows products and onedrive. Now when I want to change my password, it says unavailable and I have to enter code from Microsoft Authenticator app presumably on my boss’s device. I don’t want this. How can I setup my computer so that I log into my Microsoft account and then still receive my work’s Microsoft account’s products and onedrive?
Windows Sandbox
I had to reinstall my computer after the NVMe drive failed and was replaced. The current version of Windows is Windows 11 Business, version 25H2 (OS build 26200.7462). I enabled Windows Sandbox. However, it fails to run with the error: “Windows Sandbox failed to initialize. The media is write-protected (0x80070013)”. I previously had this Windows optional feature enabled without any issues. I have disabled BitLocker, turned off some core isolation features, disabled other Microsoft Defender anti-virus features and in addition followed some recommended steps in Microsoft Support documentation. However, the issue persists. Any help would be greatly appreciated.
