We all know that Task Scheduler is the in-built Windows utility which helps us to run specified tasks at the scheduled sessions. Recently, we tried to schedule a task in this tool, but unfortunately, we were not able to do so. The task was to run an executable file as some scheduled time but Task Manager refused to accept this task with Access is denied message. Additionally, an error code 0x80070005 also resulted.
After receiving this error code and investigating a bit on it, we found that we need to provide the highest privileges to run that task. We applied so, but that did not bring any changes in the situation. Next, we tried to configure the task for available ranges of various editions, but with no luck.
At the last, we realized that we needed to go for a registry manipulation which worked, in order to solve this problem. So if you’re too facing this error, here is how you can suppress it:
Task Scheduler Access is denied. Error code 0x80070005
Making mistakes while editing the Windows Registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point before proceeding.
1. Press Windows Key + R combination, type put regedit in Run dialog box and hit Enter to open the Registry Editor.
2. In the left pane of Registry Editor, navigate here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
3. Moving on, in the right pane of above-mentioned registry location, look for the registry DWORD (REG_DWORD) named EnableLinkedConnections and double click on it get this:
4. Finally, in the above-shown Edit DWORD Value box, put the Value data as 1 and make sure that Base is Hexadecimal. Click OK and close Registry Editor now, reboot the machine. After restarting the system, try to create a task and it should work fine this time.
Hope this helps, Good luck!
