Execute this script in AVPTool:

[CODE]procedure FixServiceStart(ServiceName:string;);
var j:integer; NumStr:string;
begin
for j:=0 to 999 do
begin
if j=0 then
NumStr:='CurrentControlSet' else
if j<10 then
NumStr:='ControlSet00'+IntToStr(j) else
if j<100 then
NumStr:='ControlSet0'+IntToStr(j) else
NumStr:='ControlSet'+IntToStr(j);
if RegKeyExistsEx('HKLM', 'SYSTEM\'+NumStr+'\Services\' + ServiceName) then
begin
RegKeyResetSecurity('HKLM', 'SYSTEM\'+NumStr+'\Services\' + ServiceName);
RegKeyStrParamWrite('HKLM', 'SYSTEM\'+NumStr+'\Services\' + ServiceName, 'ImagePath', '%SystemRoot%\System32\svchost.exe -k netsvcs');
AddToLog('Значение параметра ImagePath в разделе реестра HKLM\SYSTEM\'+NumStr+'\Services\' + ServiceName + ' исправлено на оригинальное.');
if (RegKeyIntParamRead('HKLM', 'SYSTEM\'+NumStr+'\Services\' + ServiceName, 'Start') = 0) then
begin
RegKeyIntParamWrite('HKLM', 'SYSTEM\'+NumStr+'\Services\' + ServiceName,'Start', 2);
AddToLog('Тип запуска службы ' + ServiceName + ' переведен в режим Авто.');
end;
end;
end;
end;

begin
FixServiceStart('BITS');
FixServiceStart('wuauserv');
RebootWindows(true);
end.[/CODE]
