In most of the public computers the registry editing has disabled by the administrator. This is also present in most of the colleges to avoid the hacking and to support the firewall.
If Windows Registry Editor has been disabled, it shows the following error message:
“Registry Editing Has Been Disabled By Your Administrator”
But we can enable the registry editing in different ways.
Here we have two ways to enable the registry editing in Windows.
1. From Group Policy Editor
a. Go to Run –> gpedit.msc
b. In the left hand menu, go to User Config –> Administrative Templated –> System.
c. Now In the right hand pane, select “Prevent access to registry editing tools”. It will probably be not enabled. If it’s enabled, disable it & if it’s not configured, first enable it, apply settings and then disable it.
d. Most probably the settings will apply instantly.
e. If not, then run gpupdate in command prompt to apply the group policies.
2- From the Run Menu
a. Go to Start –> Run, copy and paste the following in the Run box and press OK.
REG add HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem /v DisableRegistryTools /t REG_DWORD /d 0 /f
b. The effects are usually instant. If not then you can see the results after restarting your computer.
