Uninstall Windows 10

I uninstalled Windows 10 Technical Preview from my PC and reinstalled Windows 8.

I liked the design of Windows 10, but I couldn't do my work well because the OS frequently froze.

It took about 5 hours to reinstall the OS and softwares.

From this time, I'd like to refrain from jumping at anything new.

今日は、私のPCからWindows10テクニカルプレビューをアンインストールをし、Windows8を再インストールしました。

Windows10のデザインはそこそこ好きでしたが、頻繁にフリーズするようになってしまったので、仕事になりませんでした。

OSとソフトウェアを入れ直して前の状態に戻すのに、およそ5時間かかりました。

新しいものが出たらすぐに飛びつくのは、今後控えようと思います。

Oh no. Hope your programs are running properly now.
It's always tempting to update to a new OS but then the regret sets in after 10 minutes. Haha
