Windows 7: Unable to connect to adhoc wireless networks :(

Unable to connect to adhoc wireless networks :(

I previously bought a used laptop running Win 7 Ultimate which I am the administrator and for ages I have wondered why I am always unable to connect to adhoc wireless networks, connecting to wireless access points have no issue though.

Connecting to adhoc networks always gives me the 'your network administrator has blocked you from connecting to this network' message. I recently found out, as below there seems to be a group policy set in place?

Can anyone show me how I can disable this policy please, without having to reinstall windows 7 again as that would really be too much effort for me

Many thanks in advance!

C:\Users\admin>netsh wlan show filter

Allow list on the system (group policy)
SSID: "WL", Type: Infrastructure

Allow list on the system (user)

Block list on the system (group policy)
SSID: "", Type: Adhoc

Block list on the system (user)

I have tried using 'netsh wlan del filter permission=denyall networktype=adhoc' but that doesn't seem to solve the issue as it seems to be a group policy thing.

Does anyone know how I can get rid of the issue? Maybe via the registry?

As a one off you can go to Regedit and find Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Wireless\GPTWirelessPolicy and find the policy file location in the PATH sting.
(not sure if it is always a .tmp file in c:\windows\wlansvc\policies)

Then edit that file (as admin) and delete:

Then save, exit and reboot (not connected to your network).
Settings will be reset on the next network logon or when reconnecting to the network after a while through the policies.
