How to Repair the Windows Update Files.
1. Go Start > Run.
2. In the box type REGSVR32 WUAPI.DLL > Enter.
3. A message saying, "DllRegisterServer in WUAPI.DLL succeeded" will appear
> OK.
4. Now it is necessary to repeat these steps for each of the following files
commands:
Hit Enter after each line
REGSVR32 WUAUENG.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL
Once finished; since the temporary folder of Windows Update may be
corrupted, please carry out the following steps to rename the folder:
1. Go Start > Run > in the box type cmd > Enter.
Type the following command in the open panel.
net stop WuAuServ
(Please Note: the computer may need to be rebooted before the net stop
command will work.)
2. Go Start > Run > type in the box %windir% > Enter.
3. In the opened folder, rename the folder ( by Right clicking)
SoftwareDistribution to Sdold.
4. Go Start > Run > type in cmd > Enter. In the open command pane, please
type:
net start WuAuServ
Once that's done, Go Start > All Programs > Windows Updates and see if it
will allow the downloading/installation of Windows Updates.
