What is the Win10 TH2 update card at 44%?

Soft pushed the Win10 TH2 update to the user last night. As with every previous update, there are always users who will encounter problems during the upgrade process. In the Microsoft Q&A community today, users reported that the system upgrade card was somewhere, resulting in the update not being completed normally. The specific performance is: When the upgrade process is started, the program stops responding when it reaches 44%.
The answer to this Microsoft project is:






























In response, we are investigating this issue. ”
“If you are experiencing a 44% problem with the card, check if the device has an SD card, please remove the SD card and the installation progress should continue. If you want to insert an SD card for extra space (for upgrading the system), and the device has a USB or Mini-USB interface, you can use these interfaces instead. Otherwise you need to find a way to free up the space you need from your hard drive. & rdquo;

In fact, this problem has already appeared since the push to the Insider users, but Microsoft still has not found a solution.
