HP Officetjet 6500 E709N, Scan option does not work [Solved by using webscan option]

When you use the the printer scan buttons, the printer's LCD display will show: "select computer" and an arrow pointing to the right, and when you press the right rocker switch to "select the computer", nothing happens.
I tried uninstall and reinstall of thee full software package which is over 300MB and includes a lot of things I did not find useful and the result on the printer's display was the same.

The best thing is , in order to get your scanning working again you don't need additional software.
You only need to enable the webscan option:

Check your IP address of the printer, in my case it was 192.168.1.22 and you add that into your browser and you will be presented a webpage that shows on the left side the option to use Webscan:

 

[Solved] 2 issues during upgrade of preinstalled win8 64 bit to 8.1 (Dell Inspiron)

I ordered a Dell pc (Feb 2014) which came preinstalled with win8_64 and after getting all the updates I was offered the upgrade to win8.1. When I clicked on the upgrade in the Microsoft store I was confronted with the following screen which told me I have to retry with administrator account. I checked my fresh created account and I was administrator. Luckily I found the answer here:

• Navigate to Control Panel > Uninstall a program > View installed updates (located on the left pane) > Uninstall the Microsoft Update KB2871389

After doing this you can go back to Microsoft Store and your download will start ..

Next I ran into the issue that The installation stalled at 63-64%, to get it moving again just disconnect from the internet as was mentioned here. You can go back to your upgrade to Win8.1 tile and your installation will continue and soon be progressing beyond 63%
