No virus, adware, malware or YouTube account registration. Please see the following user guide of downloading a 4K UHD video clip from YouTube:

Step 1. Free download, install the best free 4K downloader, and launch it when you are in need of use by double click the software icon. You would note that the Hardware Accelerator (at the right side of the main panel) will be auto ticked as long as your computer sports with the corresponding GPU HW acceleration tech. This matters a lot for boosting 4K video downloading speed and improving system responsiveness.

Warm Prompt: please enlarge your hard disk to 1TB if you're going to download a long 4K video to your desktop. Usually a 2h13m 4K GoPro video (shot by 30FPS/60Mbps in H264 codec) eats up 64GB storage space and the 4K iPhone video with the same parameter settings occupies roughly 42GB space. So do the 4K video downloading mission on a desktop with high-end hardware configurations.

Step 2. Go to YouTube official site and find the 4K video source you wanna save.

Step 3. Click +(add) button, Ctrl C & Ctrl V the 4K video URL. Click "Analyze" button and select among the resolutions/sizes listed.

Step 4. Hit Download button and go. The downloading speed is jointly decided by your network connection, 4K video source (length, parameter settings..), computer hardware configurations and downloader. Hence, take all these factors into consideration if you want fastest speed.

Attention: You may find that the downloaded 4K videos are not in real 4K 3840x2160 or 4000x3000 resolution. Instead, they come to your desktop with 1080p HD resolution. Why? Causes are:

1. The 4K video footage you download probably is an upscaled version of 1080p or 2K video, which is usually called fake 4K. Therefore, it's not the 4K video downloader to blame, but the video source. Check to know more detailed difference between real native 4K and fake upscaled 4K.
2. To download 4K videos from Vimeo, please upgrade your membership to Pro or Plus level. Only Pro and Plus members can successfully get real 4K video downloaded from Vimeo. As for the free membership users, what you save is the 1080p HD version.

If you find any error in 4K video playback after downloading, please don't rush to reach conclusion on the 4K content downloading failure.
It might be the 4K video format issue. Convert 4K video codec from VP9 to H264/HEVC and change video format from MKV/WebM to MP4 for better compatibility. In case this still doesn't work, then you need to check if your hardware configurations meet the minimum requirements for 4K playback.
