Does any one suggest me trying this, what issues can I get if it goes wrong?
There has been some investigation over this issue under Windows 7. It is suspected that it’s to do with an in correctregistry key, this is the information that we have received from our support teams.

A workaround has been given to correct this registry key issue:
Before uninstalling and reinstalling the modem driver, you will need to add or modify your registry files.
For customers with internet access please download and double click the following registry file http://uploads.vodafone-ets.co.uk/Public/v...ror31RegKey.reg and begin the process below at step 6.
1. Go to start menu
2. Run ‘regedit’
3. Open this key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E96D-E325-11CE-BFC1-08002BE10318}
4. In this key, find the “Installer32” string.
5. If the Microsoft Registration Key is missing, the key has to be added manually.
6. Create a “string” value named “Installer32”, and set it to “mdminst.dll,ClassInstall32”
5. Save the ‘regedit’
6. Open the device manage
7. Find the modem with problem; update the modem driver again by reinstalling VMC 9.4.4
