如何重置此PC並重新安裝Windows

重置電腦並重新安裝Windows可以解決系統緩慢或需要全新開始的問題。通過“重置此電腦”功能，可選擇保留個人文件或徹底清除所有數據，適用於系統仍可正常啟動的情況；若無法啟動，則需使用可啟動U盤進行安裝；操作過程中需注意備份數據、驅動程序缺失和激活問題，並避免誤刪恢復分區。步驟包括：1. 使用內置重置功能或創建可啟動U盤；2. 根據需求選擇保留文件或完全清除；3. 按照提示完成重裝過程。

If you're dealing with a sluggish PC or just want to start fresh, resetting your computer and reinstalling Windows can be a solid solution. It's like giving your machine a clean slate—removing bloatware, clearing out bugs, and potentially boosting performance.

What “Reset this PC” Actually Does

When you reset your PC in Windows, it removes installed apps and settings but gives you the option to keep your personal files or remove everything entirely. Reinstalling Windows through this method is straightforward and doesn't require external tools unless you're going for a clean install from scratch.

• Keep my files – Removes apps and settings, keeps personal files
• Remove everything – Wipes all data and reinstalls Windows

This feature works best when your system is still bootable and accessible.

How to Use Built-in Reset Options

You don't always need a USB drive or installation media. Windows has a built-in reset function that does most of the work:

1. Go to Settings > System > Recovery
2. Under "Reset this PC," click Get started
3. Choose whether to keep your files or remove everything
4. Follow the on-screen instructions (this may take 30 minutes or more)

This method is ideal if your PC is still working but you want a fresh start. If Windows won't boot, you'll need another approach.

How to Reinstall Windows from Installation Media

If your system is unbootable or you want a completely clean install, creating a bootable USB drive is the way to go:

• Download the Windows 11 ISO (or Windows 10 if needed)
• Use Microsoft's Media Creation Tool to make a bootable USB
• Insert the USB stick, restart your PC, and enter the boot menu (usually by pressing F12, Esc, or Del during startup)
• Select the USB as the boot device and follow the setup steps

During installation:

• Choose Custom: Install Windows only (advanced)
• Format the main partition and proceed with the install

This method wipes everything, so back up important data first.

Things to Watch Out For

A few common pitfalls can trip you up:

• Drivers missing after reinstall – Especially with Wi-Fi or graphics drivers. Consider downloading them beforehand or using an Ethernet connection.
• Activation issues – Windows 10/11 usually activates automatically if it detects a digital license linked to your hardware or product key.
• Not backing up properly – Even if you think you've saved your files, double-check.

Also, some laptops come with recovery partitions. If you're formatting the drive manually, make sure not to delete the recovery partition unless you know what you're doing.

基本上就這些。 It's not overly complicated, but there are enough steps where one small mistake could cost you time or data. Take it step by step, and you should end up with a clean, fast Windows install.
