I'm confused about that too.
InterDigital seems to claim that the patent in question is about dynamically overlaying multiple video streams e.g. from https://ir.interdigital.com/news-events/press-releases/news-details/2025/InterDigital-awarded-injunction-against-Disney-by-German-court-5ad043c60/default.aspx
The Munich Regional Court ruled that InterDigital is entitled to an injunction over Disney’s infringement of an InterDigital patent related to the streaming of video content using high dynamic range (HDR) technology. Disney can appeal the decision.
The judgment from the Munich court follows a separate decision from the same court to award InterDigital an injunction over Disney’s infringement of a patent which enables a method for dynamically overlaying a first video stream with a second video stream. It also follows a decision by a court in Brazil, to grant a preliminary injunction in InterDigital’s favor, after the court found that Disney infringed both of the InterDigital patents-in-suit.
What's interesting is that HDR10 is still available on Disney supposedly. So it sort of sounds like the claim is that Disney is adding DV with HDR10+ fallback dynamically during the video stream.. and maybe regular HDR is pre-generated by Disney hence is not affected by the patent. The solution might be to always have multiple pre-generated copies of video before the stream even takes place..that would be a lot of extra storage space Disney would need!
Mainly the users folder(s) e.g. c:\users\YOURUSERNAME , the hidden appdata\local and appdata\roaming folders in there probably contain way more than you actually need to back up but you could back up the whole thing to be on the safe side. Most of your user's program configuration data is in those folders.
Sometimes systemwide program config data is in the hidden c:\programdata folder but I wouldn't back that up aside from specific programs you really want to save config info for.
Aside from that any other folders you created containing data you care about.
And like the other comment mentioned, the Windows registry also has lots of program config data but I usually skip that, the majority of it is useless.. but if there's a great need for you to export a specific registry tree you could do that via the command prompt to export to a backup text file. I think reg export would do it https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/reg-export
