Windows Defender Cannot Be Activated After Uninstalling Comodo Anti Virus– Help Needed (Windows 10)
Hello Community, I’m experiencing a problem with my Windows 10 laptop and hope to get some guidance. Official support is no longer available for my system, so I’m turning to the community for help. Problem Comodo Anti Virus /Internet Security / Internet Security Essentials had been installed on my laptop for a long time. While Comodo was active, I could not load certain websites properly, and games like League of Legends would not run. For this reason, I recently uninstalled Comodo. After the uninstallation, the previously blocked websites and games work again. Current issue: My Windows Defender Antivirus cannot be activated. In Windows Security, it shows: “Virus & threat protection: Action required” “The threat service has stopped. Start it now” Clicking “Start now” only shows a loading indicator and then an “An unexpected error has occurred” message. I have administrator rights, but Defender still cannot be activated. Steps I’ve Tried 1. Registry checks Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Checked entries like DisableAntiSpyware and DisableRealtimeMonitoring Modifications often failed → access denied 2. PowerShell commands Set-MpPreference -DisableRealtimeMonitoring $false → errors: “Parameter not found” or “Access denied” Other commands like Set-ItemProperty or Set-Content → errors: “UnauthorizedAccessException” or “InvalidArgument” 3. CMD / SC commands sc config WinDefend start=auto Error: “SC Open Service Error 5 – Access denied” 4. Service check Get-Service WinDefend | Select-Object Status, StartType → Status: Running, StartType: Automatic Despite the service running, Defender cannot be enabled in Windows Security 5. System restore point created (For Comodo Revomal Tool) Drive C: protection enabled Backup created as a precaution Insights / Analysis (Speculations) After uninstalling Comodo, websites and games work again → this suggests that Comodo previously installed network filters or drivers that blocked them. It is possible that remnants of Comodo (drivers, services, registry entries) are preventing Windows Defender from starting. Firewall, App & Browser protection, and Exploit protection are active → partial protection, but Defender is not functional. I am not certain if there are other causes, but based on my experience, it seems strongly related to leftover Comodo components. Has anyone experienced similar issues where Defender remains blocked after uninstalling Comodo? Are there safe methods to fully reactivate Defender without risking system stability? Should I use the official Comodo Removal Tool to remove all remnants? Are there alternative steps to try before using a removal tool? I would greatly appreciate any guidance, tips, or steps I can try to get Windows Defender working again. Thank you in advance!
Sudden crashes and BSOD in Win10
Hello! I have an Asus Vivobook 15, that came with Keep-OS and I installed Windows 11 using the official website and step by step. Last week it started crashing and having BSOD's, getting stuck on boot and sometimes not even recognizing the OS (win11). It started after a Win Update. Since I haven't found a solution and Asus does not care for the consumer, had no alternative and downgraded to Win 10. I'm still facing some crashes and BSOD. I checked the SDD, manually and with Crystal Disk Info (98% health), checked the fan... I really don't know what else to do. https://1drv.ms/u/c/7f13816d644baeb5/IQCrQrt8VfRkRZAOG5BT6By0ASV3wLkzdMiLZ-ctbrSsW84?e=PTUVlN Here is the System Events Log.Windows 10 ESU – Registrierungsbutton erscheint nicht trotz 22H2 (Rollout-Basis)
Hallo zusammen, ich möchte mein Windows 10 Pro-System für die Extended Security Updates (ESU) registrieren. Alle Voraussetzungen sind erfüllt (Version 22H2, Build 19045.6396, aktuelle Updates installiert, Microsoft-Konto aktiv). Trotzdem erscheint in Windows Update keine Schaltfläche „Jetzt registrieren“. Der Microsoft-Support hat mir heute bestätigt, dass der ESU-Rollout phasenweise fortgesetzt wird, auch nach dem 14. Oktober, nur Geräte unter 22H2 vom Supportende betroffen sind, und dass mein System automatisch berücksichtigt wird. Da ich mein Gerät gern rechtzeitig registrieren möchte, um Sicherheitsupdates nahtlos zu erhalten, meine Frage an das Entwicklerteam: Gibt es einen bekannten Zeitrahmen für den weiteren Rollout der ESU-Registrierung an 22H2-Geräte, oder spezifische Regionen- bzw. Kontoabhängigkeiten? Vielen Dank und viele Grüße Matthias
0x000000e blue screen error on boot after mbr2gpt
Hello, I just tried converting my boot disk to gpt in order to upgrade to Windows 11 from 10. I don't have screenshots on the cmd while doing so, but I remember it said it was successful. I have disabled CSM support and enabled Secure boot and made sure it says secure boot is active on the BIOS as well, but I still get this error when trying to boot. I do have 2 identical boot options which I've read can happen after mbr2gpt, but neither seem to work. I am able to boot in safe mode and would love any help getting my PC to boot now, and while I'm fine with wiping and rebuilding windows as a last resort, I would love to not have to reinstall everything. I take being able to boot in safe mode as a sign I might just have to repair with my partitions or something so I'm hoping I don't have to reset everything. Thank you!
Windows update made dell laptop into a brick
Last security update on Jan 13th broke my laptop. Every program keeps freezing and doesn't do anything. Even when I open task manager it may run for a minute but soon it will freeze, and can't even end task. Only thing that is working is my browser. Yesterday I managed to reinstall windows using a USB and it was working again. While i was away, it forced an update and once again the same issues arise. laptop is too old to install 11, and going to try and reinstall windows again. There a way I can turn off the windows 10 update before this happens again? there is a patch, but i cannot install it. When it automated update, it bricks again and i can't install the most recent patch. it's in a never ending loop of hoping it doesn't auto update when i leave the computer on, or reinstall the OS with a usb.
