Click Start -> run -> type regedit
Now you're into Registry Editor...
To backup registry: click file -> export -> type a filename & save file
Now you have to add that registry key...
Hit the plus sign next HKEY_Local_Machine, then Software, then Microsoft, then Windows, then CurrentVersion, then Explorer
Right click on the Explorer folder and select New -> Key -> and type SCAPI for the new key name
This will add a SCAPI key (folder) under the Explorer folder.
Next, Right click the SCAPI folder and select New -> DWORD Value -> and type Flags for the value name (it will appear on the right side of the window)
Now just right click the Flags name on the right side of the screen and select Modify
Type 100c02 under the Value Data, leave it as Hexidecimal -> click OK
That's it! You should now have a SCAPI folder under the Explorer folder on the left and inside the SCAPI folder (on the right side) you will see the default REG_SZ and the REG_DWORD you just added.
Close registry editor and see if your problem is still happening. No need to reboot.
Post on here if it works or not.
