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
Local account and MS account
I just did a windows 11 Home clean install and used my MS account for the installation. (Ready for the planned deactivation of local accounts.) Now I have two home directories and Windows is using the new MS account directory structure, but all my active files are in the local account directory structure. These questions will sound stupid, and they are, so we got that covered. Please reference howto documents. If I should read/study a book, please point me to the best Windows 11 Home admin book. How do I tell which UID I'm using? How to find the correct profile I'm using. Can I delete the local user account without deleting the active files? How to merge the two account files to the true active MS UID? Thank you, Ed T.

Thank you for your support. #Windows11, #Windows 11 24H2, Windows Update, Cumulative Update, System Freeze, Lenovo ThinkPad, Display Driver, EnterpriseThis is why you should switch to Windows 11
A lot a people criticize Windows 11 for bloats and what so ever but actually Windows 11 has great features such as Game bar (if you're a gamer), Phone link which you can send photos from your PC/Laptop to your Phone (works for both Android and Iphone) And best of all Task view which is very important because you can open Microsoft Word/Excel/Powerpoint while chatting on Microsoft Teams or Whatsaap. Windows 11 maybe bad but still it has great features.
EFS Certificate Lost After Format – Files Cannot Be Decrypted
Windows installation. I formatted Windows and copied the encrypted files to an external hard drive before formatting. After reinstalling Windows and signing in with the same Microsoft account that was linked to the original installation, the EFS certificate is no longer available and files cannot be decrypted. Error: "The specified file could not be decrypted" Command tried: cipher /d — returned ERR on all files Important detail: After the new Windows installed, I saw the Windows.old folder and permanently deleted it using Shift+Delete, thinking it was unnecessary. During deletion, some files showed an error saying they could not be deleted. I believe the EFS certificate (.pfx) may have been inside Windows.old — is there any chance it still exists on the drive since some files failed to delete? Can you help recover it? These files contain irreplaceable personal memories. Any help is appreciated. i really really need those files and many files as soon as possible if you know how please help me.
