我试图解释 的结果wmic nicconfig list full，但我不明白 的含义DNSEnabledForWINSResolution。
如果我考虑名称，我会认为如果我尝试使用 WINS 解析名称但没有这样做，那么将尝试使用 DNS。
但是，根据微软相当模糊的文档（https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-networkadapterconfiguration），情况正好相反：如果无法使用 DNS 解析名称，然后将尝试 WINS。这对我来说听起来不太明智，但我认为描述说明了这一点。
那么是哪一个呢？
我有一个视频，一个屏幕录像：recording00.mp4。我用FFmpeg压缩它：
ffmpeg -i recording00.mp4 -c:v -libx264 -pix_fmt yuv420p -crf 27 -preset veryslow output00.mp4
如果我再次用相同的参数压缩 output00.mp4，会发生什么？
质量会下降吗？
文件大小会减小吗？
我问这个是因为我在不同的日子创作这些录音。我希望它们占用最少的磁盘空间，所以我在录制后立即对它们进行编码。当它们中的最后一个完成时，我将它们与以下行连接起来：
ffmpeg -f concat -safe 0 -i list.txt -c copy whole.mp4
问题是文件之间应该有很多协同作用（真正相似或相同的帧），但是，whole.mp4 的大小大约是 outputxx.mp4 文件的总和。
我想用第一个命令重新编码它们，但我担心它会降低质量，因为我不确定这个 CRF 参数是相对值（相对于输入质量）还是绝对值。
我的意思是如果它是相对的，那么最后是 60% * 60% = 36%，如果是绝对的，那么即使我重新编码两次，它也会是 60%。（60% 只是一个虚构的质量衡量标准。）这个 CRF 是哪一个？
在 PowerPoint 中，您可以从功能区设置形状的宽度和高度：
我怎样才能对它的位置（x 和 y 坐标）做同样的事情？
我知道我可以单击十亿次并通过对话框进行设置，但从功能区设置它（如宽度和高度）是有意义的。（我知道 PowerPoint 是 Microsoft Office 中质量最差的，它的开发人员没有做出明智的选择，但也许我很幸运，有这样的功能。）
我想在我的 Windows 机器上自定义文件夹视图。
我找到了以下注册表项，并将它们的 LogicalViewMode 值设置为详细信息、列列表等。
我不得不使用 psexec 因为这些键被锁定。
但是，在进行这些设置后
(1) 文件夹仍然不在详细视图中，
(2) 在开始菜单中键入不会开始搜索。
所以，我想了解“TopView”到底是什么，为什么会有 80 多个以及它们各自的作用，因为它们的名字并没有真正的帮助。
