If an update, a mistake, a bug or a malicious program breaks something on your computer, you can restore the operating system from any snapshot, thus cancelling the problem as if it never happened.

如果更新、错误或恶意程序对计算机造成了破坏，您可以从任何快照恢复操作系统，从而取消问题，就好像它从未发生过一样。

System snapshots only cover the operating system itself. They do not include or affect your personal data.

系统快照仅仅覆盖操作系统本身。他们并不包括或者影响你的个人数据。

When an update breaks something, it's called a "regression".
|

|
|
|
“回退”是指由于更新而产生错误。

Updates keep your computer safe, eliminate bugs and even sometimes add new features to your operating system.

更新可以让您的电脑保持安全，修复存在的错误，有时还会带来一些新特性。

Unfortunately they also sometimes introduce new issues called 'regressions'.

不幸的是它们有时会造成“回退”。

Regressions are very common in the software industry. They're inherent to software development. Code changes can cause regressions. No matter how skilled developers are, they can't always predict every possible situation or test on every possible hardware specification.

在软件开发中回退是无法完全避免的，其在软件产业十分常见。修改代码就有可能造成回退。无论开发者技术多么精湛，也无法预测每一种可能发生的情况，也无法在每一种硬件环境进行测试。

When a regression happens, it breaks something which worked well before.
|
|
|
|
|
回退发生意味着原有的某种可以正常使用的特性发生了错误。

Sometimes it doesn't really matter, but sometimes it matters a lot.

有时它并不会影响使用，但它也有可能带来严重的后果。

It depends on what part of the operating system is affected and whether or not you're able to work around it or to fix it.
|
|
|
|
|
这取决于它影响到操作系统的哪一部分，以及您是否能够解决或修复它。
