C&C Game is german And Censored ...

Are you using The Ultimate Collection or old CD-version? The CD-versions indeed don't work with Windows 10.

Are you talking about The First Decade, or The Ultimate Collection? As far as I know, the Ultimate Collection should use the language set in your profile.

Do you actually live in Germany, though? In Germany, they only sell the censored version. There are a multitude of patches available to uncensor the game though, and the first three games are completely freeware, so for these you can simply download the freeware English releases.

If you do not live in Germany, though, and think you got this German-language version by mistake, I suggest you contact an Advisor via EA Help and get a live chat session. These people can actually look into the system and your account details to solve such things.

A lot of the games have been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. I know for a fact the C&C1 and RA1 patches uncensor the game. You can find them here:

Command & Conquer 1:

• Nyerguds' C&C95 v1.06c revision 3 patch (which also adds bonus missions originally exclusive to the Playstation and Nintendo 64 versions of the game)
  Note that this patch fixes two quite common and completely fatal game crashes (top-of-map reconnaissance crash, stealth crash), so installing it is strongly advised.

Red Alert 1:

• Funkyfr3sh's automatic Red Alert 1 patcher/installer (The thread also has briefing videos for the expansion missions, converted from the Playstation version of the game)
• Nyerguds' main.mix cleanup for TFD/TUC (Not really needed, but cleans up about a gigabyte of unnecessary files in the RA1 folder. Unpack in the game folder, run "patch_main.bat", let it finish, and then delete the files you extracted.)

Tiberian Sun:

• Funkyfr3sh's Tiberian Sun patch

Red Alert 2:

• I advise installing the CnCNet online play installer for RA2/YR. Even if you're not interested in online play, it comes with a bunch of automatic fixes. It should automatically take care of the "black screen" issue, and has a configuration tool that allows further tweaking of the game's settings.

Generals:

• GenTool seems to be the main patch for Generals these days. The website is kind of vague on what it does besides restoring multiplayer and adding anti-cheat, but I heard it does a lot to make it work better on modern OSes too.

Renegade:

• The Tiberian Technologies patch fixes loads of issues on Renegade.

Uncensored video packs for C&C1, RA1 and TS can be found here.
