Hello,
Sorry to hear you are having issues. Please provide more information.
1) Windows version. Please use Winver.exe for full version numbers.
2) Installed Windowblinds version.
3) Need to know why you think Windowblinds is causing your internet speed drop. As far as I know, Windowblinds does not effect internet speed. Have you tried uninstall and try again.
Thanks
