I had a problem with getting Microsoft/Windows updates and messages about WMI. tried general fixes that are recommended, i.e., change Registry Values, uninstall anti-virus program and replaced it with a different one, ran a
battery of tests to make sure that my pc doesn't have any malware/viruses/trojans/hijackers, and none were found. I received a bunch of suggestions from MS that included making batch files and .exe files and clicking on them. I was then able to get Microsoft/Windows updates again and the first bunch of updates consisted of over 30 updates. I lost internet connection right after they downloaded and installed so, without pointing fingers, it could have been a number of things that caused me to lose connection to the internet, but it isn't hardware related.
The only reason I knew anything about ipconfig is because I used to have to forward ports for a program that I use and I needed the ipconfig info for it.
What started this whole process is interesting. I decided to Repair Windows, as I've done several times over the past years, to get rid of the little bugs (not viruses) that crop up. The first thing I usually do after doing a Repair is to go to MS Update, but there were no updates. I did a lot of reading on the internet and it led me to this, from Microsoft:
I was able to resolve this problem but another problem arose, with a file named WUAUENG1.dll (or WUAUENG.dll). This was solution that Microsoft gave me and it worked:
Click Start, Run, type: notepad C:\AU.reg and press Enter. Choose Yes
when you are prompted.
2. Copy the following text and then paste them into the opened Notepad window:
Windows Registry Editor Version 5.00
"Description"="Enables the download and installation of Windows updates. If
this service is disabled, this computer will not be able to use the Automatic
Updates feature or the Windows Update Web site."
3. After we paste the above text, please close the Notepad window. Choose
Yes when you are prompted to save the file.
4. Click Start, click Run, type in REGEDIT and press Enter.
5. Locate the following key by clicking the PLUS(+) sign:
6. If this key exists, please right click it and select Delete.
7. Double click C:\AU.reg to import the registry key and select OK.
8. Restart your computer.
So, as you can see, I've been around the mill a few times over the past week.
My own thoughts: If anyone has Windows XP Pro x64, all of the above steps might need to be taken after a format or Repair, including loss of internet service, inability to get MS/Windows Updates, WMI, WUPS, and WUAUENG1.dll.
