Recreating corrupted wireless network profile in Vista

by on Sep.03, 2010, under Windows

If Windows Vista prompts you to enter the Wirless password everytime after reboot even after you save the password, you might want to know something is wired with Windows Wireless Management.  Wireless Management is not saving your passwords and matter of fact not even the profile. You can verify it by going to Network and Sharing > Manage Wireless Networks option.

This means your Wireless profile setting is corrupt and it is better to recreate so that Windows Vista starts saving the wireless profile and password. Follow below steps to recreate the profiles.

  1. Goto Windows Services and Stop WLAN AutoConfig service.
  2. In regedit find the following key and delete all the sub keys under it.
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWlansvc
  3. Now go back to Windows services and restore the WLAN AutoConfig service
  4. Add the wireless profiles again and save the password. The wireless profiles will start appearing in your Manage Wireless window.

Hope this has helped your resolve the issue. If you have any questions please let me know.

Disabling compressed files (ZIP/CAB) search in Windows XP/Vista

by on Jun.11, 2009, under Windows

Windows XP / Vista have a built in feature of supporting compressed archive files. The file types supported are .zip and .cab. Windows treats these as folders and displays it in the windows explorer tree and also includes these files during the search. This would a hindrance to the users who had used their favorite compression utility like winzip, winrar or 7-zip in their previous versions of operating system. Windows file search functionality will be slow when there are lots of compressed files in the search folder. We can overcome this hurdle by disabling this feature. This can be later enabled when required.

For Window XP to Disable

1. Open start > Run

2. Type the command regsvr32 %systemroot%zipfldr.dll /u

3. Press ok on the popup message

4. The change will take effect immediately, but you may have to restart Windows for all features of the built-in ZIP support to disappear

For Windows XP to Enable

1. Open start > Run

2. Type the command regsvr32 %systemroot%zipfldr.dll /u

3. Press ok on the popup message

4. The change will take effect immediately, but you may have to restart Windows for all features of the built-in ZIP support to be available

Where %systemroot% normally is C:windowssystem32

For Windows vista to Disable

1. Open Start > Run

2. Type “regedit.exe and click ok

3. Navigate to the key HKEY_CLASSES_ROOTCLSID

4. Export the values under the key HKEY_CLASSES_ROOTCLSID{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31} and HKEY_CLASSES_ROOTCLSID{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}

(This process is to backup those keys incase later if this feature needs to be enabled)

5. Delete the keys HKEY_CLASSES_ROOTCLSID{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31} and HKEY_CLASSES_ROOTCLSID{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}

(The key keys HKEY_CLASSES_ROOTCLSID{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31} is associated with the zip file and the key

HKEY_CLASSES_ROOTCLSID{0CD7A5C0-9F37-11CE-AE65-08002B2E1262} is associated with cab files. In case you need to disable one of the feature zip/cab you can do it by deleting the corresponding keys.)

6. Restart the computer for the changes to take effect.

Alternate Method:

1. Download the reg file here

2. Double click to install

3. It is successful, restart the computer for the changes to take effect.

For Windows Vista to Enable

Connecting to a hidden administrative default share in Windows Vista

by on Oct.11, 2008, under Windows

In windows vista by default the hidden default shares like c$, ADMIN$, IPC$ and Print$ are disabled due to User Account Control (UAC) feature avoiding it to be connected in the network. So when you try to connect from other computers in the network you might possibly get the below errors.

Logon unsuccessful:
Windows is unable to log you on.
Make sure that your user name and password are correct.

You may get the below error when you try to connect using “Net Use” command:

System error 5
has occurred. Access is denied.

How to get rid of it?

There are 2 solution for this problem

  1. You can create an explicit share of the required device.
  2. You can modify the registry to enable LocalAccountTokenFilterPolicy key.

Creating explicit share for the device:

  1. Open Explorer
  2. Choose the folder or drive
  3. Right click on the folder or drive and click on share
  4. If you have password protected sharing enabled, select which users can access the shared folder and their permission level. To let all users have access, select Everyone in the list of users. By default, the permission level is “Reader.” Users who have this permission level cannot change files or create new files in the share. To let a user change files, change folders, create new files, and create new folders, use the “Co-owner” permission level.
    If you have password protected sharing disabled, select the Guest account or the Everyone account. This is the same as simple sharing in Windows XP.
  5. Click on share and then press OK

This method is safe and can be done by beginners.

Modify registry to enable LocalAccountTokenFilterPolicy Key:

Here is also an alternate which requires some expertize in the operating system. Here are the steps.

  1. In Run prompt type regedit to open registry editor
  2. Browse through the following sub key
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
  3. Create a new entry with the below information
    Key Name : LocalAccountTokenFilterPolicy
    Key Type : DWORD (32-bit)
    Key Value : 1
  4. Exit registry editor.

To disable this option modify the registry key value to 0.

Warning: If you are trying out this method user need to have a knowledge on windows registry. If some of the keys are modified incorrectly it may cause a serious problem to the operation system for proper functioning. Backup registry before doing any changes.
