Hi
Save text below as fix.reg on Notepad (save it as all files (*.*)) on the Desktop.
It should look like this ->Code:REGEDIT4 [HKEY_USERS\S-1-5-21-1060284298-1336601894-839522115-1003\Software\Microsoft\Search Assistant\ACMru\5603] "001"=- [HKEY_USERS\S-1-5-21-1060284298-1336601894-839522115-1003\Software\Microsoft\Search Assistant\ACMru\5603] "000"=-
Doubleclick fix.reg, press Yes and ok.
(In case you are unsure how to create a reg file, take a look here with screenshots.)
- Download Registrar Lite from here and install it.
- Start Registrar Lite.
- Type in to Address field this and click ok: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TFKNYKL\0000
- Right-click that key and choose Properties. Click "Take ownership".
- Right-click that key again and choose Delete.
- Repeat process for these key(s):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TFKNYKL
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TFKNYKL\0000
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TFKNYKL
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_TFKNYKL\0000
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_TFKNYKL
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_PEXWYXYBWW\0000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_PEXWYXYBWW
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_PEXWYXYBWW\0000
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_PEXWYXYBWW
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_PEXWYXYBWW\0000
KEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\LEGACY_PEXWYXYBWW
After that run registry search tool in the same way as two previous times. Post back the results.
