How to Disable Auto-Suggest
If you don’t want to use the auto-suggest feature you can disable it with the following hack.
Press the Windows Key and R to bring up a run box and type regedit, then hit enter.
When the registry editor opens, navigate to the following path:
Expand the Explorer key, then right click on it and create a new key called AutoComplete.
Once the key has been created and you have named it, on the right hand side you will need to create a new string value called AutoSuggest.
Open the string and in the Data Value field type no.
