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-af20Views0likes0CommentsWindows 11: Task Manager: Background Processes: Stop Unnecessary Ones from Starting Automatically
Greetings. For far too long, I see random instances when at least the following four unnecessary background processes are running automatically in Task Manager: Microsoft Content, Work or School Account, Windows OOBE Service, and Microsoft Store Background Task Host. I do not have and never have had a Work or School Account. I do not allow any of these applications to run in the background. Could someone at Microsoft please improve the software modules for at least the above four processes so they will not run automatically in Task Manager at random instances without my allowance? Thank you for your assistance, if indeed you offer it.5Views0likes0CommentsNo wifi in the morning
I have a really strange problem with my Lenovo pc 9i, running Win 11 Home. From 7-8am it cannot access my wifi. The problem may occur again for an hour later in the day, maybe. My Samsung Tablet, our Pixel phones and my wifes Lenovo 71 all have no problems with the wifi. I've had the local repair shop look at it. They told me it was a problem with the Nordvpn I was using so I replaced it with Expressvpn. The problem remains. Last Saturday morning it worked fine all morning, but it had slipped into Airplane Mode. Those are the clues. Any help will be appreciated. Thanks in Advance57Views0likes5CommentsBattery stuck at 44% after Windows update (HP laptop)
My HP laptop battery is stuck at 44% even when plugged in for over an hour. It shows charging, but the percentage doesn’t increase. When unplugged, the battery drains normally. This started after a recent Windows update. I’ve already tried restarting, reinstalling battery drivers, power reset, and checking BIOS settings, but nothing worked. Any solution for this?6Views0likes0CommentsHow to Completely Uninstall OneDrive from Windows 11 and Remove All Traces?
Hello everyone, Recently got a new Windows 11 laptop but very annoyed by the OneDrive app. Honestly, I've been trying to uninstall OneDrive completely from my computer. I don't just want to remove the app itself, but also clear out any leftover files and settings that may still be lingering after the uninstallation. Can anyone guide me through the process of completely uninstalling OneDrive from Windows 11 and ensuring that no traces are left behind? Any help would be much appreciated!228Views2likes10CommentsMedia driver missing error during windows 11 installation
Bought a new PC without OS and made a bootable usb using the official media creation tool. The installation went fine but got the error "A media driver your computer needs is missing" after choosing the disk to get Windows 11 installed. I have no clue about this and the error showed up again when I was trying to do it again. Hope someone could suggest a solution to get it fixed.

Hi, I am having problems with my acer aspire 5. I have very limited disk space and it says 700+gb are taken by temporary files: When I try to press on temporary files and clean it, it gives me like barely any files to clear: I have trawled this forum trying all the commands I can find but they're all making no difference! This is making my laptop unusable, any advice? TIA1View0likes0Comments
