This afternoon, I rebuilt a pc with Windows 8. That is not much problems about that, however, after I finished the process of rebuilding and trying to upgrade for Windows 10. I downloaded Windows 10 Upgrade assistant. It helped me to download the windows 10 installation files. However, the 1st attempt is failed after all files are installed, but it said more one of components are failed to configure. And it restored to Windows 7. In 2nd attempt, I unplugged all USB external devices, such as printers and scanners. Then it upgraded successfully. If you faced the similar errors, maybe you can try this method!

I got this error when I upgrade a Java Installation in Windows 10. I got the error 1603, even I restarted the computers a number of times. Finally, according to the instructions from java, I uninstalled the whole Java runtime and downloaded the offline installer rather than using online upgrade. Then that works again!

I just built a website in Bootstrap, I fount the mobile menu won't be collapsing after I clicked menu button. I tested in a number of mobile platforms, all of them are not working. After I reviewed the code, actually, that caused by referencing the bootstrap js file two times. My theory is the mobile menu won't be collapsing if the js file references more than once in the html page.

If you are considering to upgrade your office product included office suite, visio and publisher to the latest 2016, please re-consider that. This version of office cannot work with other older version office products. For example, you installed office 2013 and visio 2013, you want to upgrade visio 2013, it will ask you to uninstall 2013 first. For myself, that is a common practice, not all of my office products keep to the latest version, in the past years, I upgraded the office suite to the latest, and left visio to be one or two version older. That saved money.
However, in Office 2016 environment, this practice won't work anymore. No matters, you install older version office products first, then putting 2016 version later, it won't work. When you install any office 2016 products, it will say you got some older version office products, please uninstall them.
If you have more one than office products and you want to have a upgrade, you have to upgrade all of them!

Recently, I got a few desktops and laptops have a same problem. Suddenly, they cannot boot up into windows anymore. After the power is on, they entered a loading screen of windows, after a minute,it restarted itself. This situation repeated a few times, that is a kind of an infinite Loop of restarting. Finally, it will go to a windows boot manager. Then you can choose to enter safe mode. If you are luck enough, you can go to last restore point. I found this problem are caused by the windows update. In my cases, I had to use the restore image and did a factory reset.
