Does command and conquer ultimate edition work in Windows 8?

I can't say for windows 8. I got windows 10 & just bought the collection recently.  So I'll post my experience so far for others lurking.

All this is dealing with single player.  Not diving into multiplayer.

Generals works fine for me so far. Can't full-screen and stuff tho. Expected

I believe I needed to use a patch for RA2 to get it to work but I honestly haven't played it much yet & not aware if there are other issues yet.

I needed to patch first one and it still seems wonky so I don't play it.

Tiberium wars works fine so far. It's probably the most stable one so far on my end.

I haven't tried c&c 4 yet.

Red alert 3: Haven't played too much of it so idk about late game performance.  I can't alt tab. The game will crash and I can't close out of it.  Sometimes have to restart pc. You may experience sound issues & other quirks.  Actually can't find solutions for ra3 and I've stumbled across many threads with people having issues with it. Sad cause I was really interested in this one.

Look elsewhere is my advice unless someone wants to step in with detailed solutions.  I've had to tweak most of it to get to work & some aren't stable enough to play. I'm just disappointed with the purchase so far. They're great games but origin needs to look into this collection IMO to get things to properly work.  I believe some of these solutions online are further complicated to do because of the origin launcher.

A lot of the games have been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. 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.

Though, do note, the oldest three games are freeware. You can just download the full versions of those.
