Question: I want to remove Speeddialsearch.com from my computer for forever. It keeps coming back ...


  1. Windows 7 – Home Premium.
    Over the years I’ve tried several “fixes” for problems. Some work, many don’t and I’m afraid this is one of the latter. Going through the regedit steps (as administrator) I get the same “Unable to save permission changes on Enum. Access is denied.” as several others have had. I have tried in normal mode and safe mode. I’ve yet to find any answer to this. Presumably whatever is the problem has screwed up the Access too.

    My ‘device manager’ is still blank.

    Anyway, I’m about to resolve the problem: reformat the hard drive and reload everything. It works every time!

  2. I have the same problem as the rest (device manager blank) and tried all above and nothing worked. I do not know if it is the cause of another problem which has do with wireless connection under “IP address is not valid”

    • As you can see in above steps, it is directly cause of permissions. Might be possible your IP issue is also causing due to permission. Please follow all the steps in safe mode once if it works in safemode because only this step can solve this issue. Let us know if doesn’t solve your issue after that.

  3. nothings happened

  4. Hello! Yesterday I said that the solutions above did not work, but apparently something did as when I started my computer this morning everything was in place and the device manager was blank no more! Thank you for your assistance in this matter and for being so helpful.

    You have to take ownership of the key first. Then change the permissions…

  6. No tried this and it does not work

  7. Hi there! When i access to the enum section it appears the everyone and system sections, however it appears a third one; ‘owner rights’. I was wondering if this section makes my device manager to be in blank, if it is so, can u plz tell me how to solve it?

  8. I cant see ENUM. I still changed permissions though and sorry, still not working.

  9. is stupid. Is this guide for xp users? Coz it sez Unable to save permission on enum. Access is denied on 7. Guess all have this?

    • There are some internal permission in XP. Anyway, we suggest you to please use DIAL A FIX ^(http://djlizard.net/software/Dial-a-fix-v0.60.0.24.zip) tool to fix this issue.

  10. I’ve got the exactly the same problem too – can’t alter the permissions. Any other solutions?

  11. I’ve got same problem, registry denies access so can’t change anything. Since I’m the only person using this computer I would have thought that I was the administrator.


  12. Having the same issue. I can only use a USB mouse a USB keyboard doesn’t work Network drivers do, but it’s mobo onboard. I ran regedit as system administrator and I cannot apply the settings.

    I am not sure if this is some sort of virus but its hard to get rid of

  13. Yup tried this and Access denied. I really need a solution to this problem..

  14. same here.. I can not edit permissions for Enum. It always say Access denied

  15. No Enum

  16. Hi, tried all of this and it won’t let me apply the new settings
