Adobe Updater error: The update server is not responding

For the past several days, my copy of Adobe Reader 9.3 had been unable to update. It was also taking 10-20 seconds to open PDFs. I knew that 9.3.1 had been released, but when I tried to force it to check for updates with Help > Check for Updates, I just got this error message:
The update server is not responding, which means it might be offline at the moment, or the Internet or firewall settings may be incorrect. Please try again later.
After reinstalling Reader and adding a firewall exception didn't help, I stumbled across this Microsoft TechNet Forums post with the solution:
  1. Open Network and Sharing Center
  2. Click Change adapter settings
  3. Right-click the Microsoft Virtual WiFi Miniport Adapter, and click Disable.
  4. Open Adobe Reader and Help > Check for Updates

    I don't have a wireless adaptor and still have the problem

    The "solution" that was offered actually only works for people whose computers have the Microsoft Virtual WiFi Miniport Adapter installed, which is not the case for most Windows 7 and Windows 8 users.

    As application developers, we have (at last count) 273 programs installed on each of our workstations and approximately 70% of those programs have auto-update features built in, yet only Adobe Update Manager ever poses any problems.

    As programmers, we thoroughly understand that if hundreds of applications can successfully update themselves on any given machine, and only one program (Adobe) has problems, then the one and only program is the one and only problem.

    Adobe's developers apparently no longer know how to create software that can communicate successfully over a single port, which is the reason that this issue arises on so many computers.

    I completely agree! I am one of those that still don't have a solution, since i don't have Microsoft's Miniport Adapter installed. So what's the solution for me??

    I do have the same problem since I'm using windows 8. please update this post if you have found the solution. thanks

    I actually solved the problem. you just need to connect your PC through Ethernet connection. that did it for me. I hope it works for you.

    In case anyone else ever stumbles across this through a Google search or whatever, I was able to fix this issue on Windows 8.1 by:

    1. Go into the Device Manager->View->Show Hidden Devices
    2. Disable Microsoft Hosted Network Virtual Adapter
    3. Disable Microsoft Wi-Fi Direct Virtual Adapter

    FYI ... this problem dogged me for months. The solution above did not help me as it did not apply. I did however find a much easier solution that surprised me. I simply reinstalled Adobe Application Manager and the issue was resolved. Hope that helps others.

    The difference between burritos, chimichangas, and enchiladas

    I love Mexican food, but I'm embarrassed to admit that I always get confused between burritos, wet burritos, chimichangas, and enchiladas. Here are the descriptions, with the differences in bold and pictures following each description.

    A flour tortilla wrapped around a filling (meat, beans, vegetables, etc)

    wet burrito
    A burrito that's covered in red chili sauce and cheese. Because of the sauce covering, it looks like an enchilada, but it's made with a flour tortilla, whereas the enchilada is made with a corn tortilla.

    A burrito that's deep-fried. Sometimes covered with cheese or another topping.

    My LASIK laser eye surgery experience

    Yesterday was a turning point in my life; I had laser eye surgery (LASIK)! Here's a brief summary of my experience.

    When I was 16, I barely passed the eye exam at the DMV, so they told me I had to see my eye doctor. Being a self-conscious geek, I opted for contacts over the stereotypical glasses. Although they were fine for most of the day, my contacts always dried out around 8 or 9 PM. My friends will tell you they got sick of my complaints that "my eyes feel like corks!" and "these contacts feel like sandpaper!"

    Over the years, I've tried more than 10 different types of contacts, including extended wear, overnight wear, and high-moisture contacts. For a while, I even had contacts with bright blue artificial irises to cover my natural grayish ones. I got a lot of compliments, but they didn't help with the dryness.

    I decided to put an end to the suffering this year. LASIK isn't cheap; reputable surgeons charge about $2000 per eye. It hurt to max out my…
