Hi All,
Please follow these steps:
1. Run Registry Editor. (regedit.exe)
2. Go to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search
3. In the right pane, do you see a value named "AllowCortana"? If Yes, is it set to 0x00000000?
When this value is there and if it is set to 0, the symptom will occur.
To resolve this:
1. Delete this value and restart the computer. Then check whether Cortana works.
2. If it still does not work, check if the registry value has been re-created and set to 0 again.
3. If the value is created and set as 0 again, it is normally caused by Group Policies or local policy.
If this machine is in a Domain, check with the Company IT to verify about the group policy settings.
Otherwise, please check the local policy:
a. Run GPEDIT.MSC (Press Win+R, type GPEDIT.MSC and press Enter).
b. Locate: Computer Configuration > Administrative Templates > Windows Components > Search
c. In the right pane, find the setting "Allow Cortana".
d. Double click it and change it to "Enabled".
e. Restart and see how it goes.
Let me know if it helps.
Regards,
Bennie Chen
