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!
Windows Desktop - New Folder Type Feature
I'd love to see a new desktop icon/folder feature. Adding a specific type of New Folder that will only be displayed on your main/primary display desktop. The folder would always be visible on the main display and contain the icons that show up on all external monitors that are not flagged as the main display. That way, when a laptop isn't connected to an external monitor, those sets of icons are quickly accessible via the special desktop folder on your main display. You would no longer have a flood of icons when using only the laptop and when docked you have them at their normal positions.
