I just got something named "MediaHuman YouTube Downloader 3.9.9.33 (1802) with patch". I haven't opened the .rar archive yet, but I'll give a review after I try it out. I trust the source, so I'm not concerned that it might have malware.
If anybody else uses patched or cracked software like I do, AND uses a Windows computer, be aware that Windows updates routinely scans for unregistered software, and they usually make it unusable in the future. My unregistered copy of WinSnap v3.5.5 no longer works properly, and it's not even an installed program. I think I can get it to work properly if I do the following:
a) Delete the files currently in the extracted .rar archive.
b) Re-extract the files on a drive other than C:, preferably on a flash stick that I insert only when I want to make a screen cap.
If that doesn't work, and I want to make an image file from a web page, I can save the page as web page complete/ html, then make the screen capture from the html document, at a time when I'm not connected to the Internet. I don't think Windows would be able to detect that.
I can't do this for Youtube video downloading, but for older apps unrelated to Internet use, I have a separate computer with Windows XP that has never been connected to the Internet. I use it for work, compressing .VOB video, making computer fonts or animated gifs, or playing DOS based Wolfenstein 3D addons, or Risk II. It's superfast. I make fonts with 1995 software that doesn't work with Windows after XP, nor with XP after some update from February, 2013, and people using the latest and most expensive software on the market can't reproduce some of the things I do.
The work computer was custom built from old parts, and has XP with Service packs 1 and 2 only. I can imagine a day in the not too distant future where computers with XP that have never been connected to the Internet will be VERY valuable commodities. Total cost was $100, with no tax, because I paid cash. It's one of those old 'horizontal tower' models, with a Floppy disk A: Drive, but also separate CDROM and DVD Drives. Most of the software I use often doesn't work with the Windows o/s's from Vista to date, even if it is registered.
With Windows XP. you could read the .log files created after an update with Notepad. Most of it is in plain English. When I get a new monitor for a third computer, I'll post some of the information from older Windows updates logs.
