Stuck on preparing for installation windows 10

At the first time when i tried to download windows 10 through windows update, it looks for me like it stucks at preparing for installation... So i stopped the process, restart my windows 8.1 and re-download windows 10. Samething happened for the second time, but i have waited for about 30 minutes and i have noticed that the progress bar of preparing for installation... continued to progress very very slowly and when it reached a specific point of the progress bar it suddenly finished the "preparing for installation..." phase and jumped to the upgrade phase.

I do not really know why it progresses very slowly (maybe a background task), but I found that the best solution is to wait for a big amount of time until every thing is done.

I would suggest you use the Windows Media Creation Tool instead.
