Since many weeks I tried to programm C++ in visual studio, but the compiler always gives me 475 errors, so I thought the reson is the SDK. After changing between some different Windows SDKs it worked, but about one week later it stopped working again.

I'm not sure what you're doing, but it's not usually difficult - install VS 2022 with the "Desktop development with C++" option, then File, New, Project, and create a C++ Console App, and it should build seamlessly.
I know, because I alredy did it many times, but this time it says the system can not find the specified files.
I get these errors every time:
If you change the error list output to just "Build" rather than "Build + IntelliSense", do you get any errors when you build?
Then I only get the error C1083 cannot open file (include): "crtdbg.h": No such file or directory
It looks like something's not correctly installed on your system.
Is that header file on your system?
For me it's under: C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\ucrt
If I check a VS project's settings, under Configuration Properties, VC++ Directories, the Include Directories entry has that path (and many others) listed.
I've searched a bit in my projects folder and found an old project that works.
The left one in the picture is working the right one doesn't:
(the only differents is, that in the right one the Debug-File is in the x64-Folder)
The left one has a Debug folder there as you've done a 32-bit build at some point. I'm fairly sure that's not a reason for the compilation failure. Have you checked what I said previously?
Yes, the header file is on the system.
... and is that path one that the Include Directories has listed?
Where can I find the include directories?
Read my earlier reply again.
I checked again, the header file is in C:\Program Files\Microsoft Visual Studio\2022\Community
Is that path in the Include Directories entry of you project's settings, under Configuration Properties, VC++ Directories?
I'm surprised it's there rather than under a Windows Kits directory. If you run the VS Installer, check under "Individual components" if you've got a Windows SDK installed:
snipped duplicate post
SDK is installed that was the first thing I checked.
Do you mean that:
Do you mean that:
Yes, and if you open that item up (click its drop list and choose Edit...), it'll show you the actual paths that are being used.
Given that you appear to have the SDK installed, I'm surprised the header file isn't in a different location. Are there multiple occurrences of the header file on your system?
It seems like there is only one header file
Given the information at hand, I don't know what's gone wrong for you.
As a first attempt to remedy the situation I'd close VS, then use the VS Installer and uninstall the Windows SDK components. Reboot (just in case), then use the VS Installer and add a Windows SDK back.
I tried, but it didn't work.
OK, uninstall VS and re-install - after that I'm out of suggestions.
I already have tried to reinstall it, but it didn't work.

Hi @Clemens Fischer ,
Welcome to Microsoft Q&A!
Does it occur in all projects or specific project?
As you said, you changed the Windows SDKs before. Can you install the Windows 11 SDK (10.0.22621.0) via Visual Studio Installer?
Then, run VS as administrator and change the Windows SDK Version in project property to the latest version.
Besides, the crtdbg.h should be located at C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\ucrt.
If you find the crtdbg.h on a different path, please copy the directory path where the crtdbg.h is located.
Then, manually add the path into Include Directories and rebuild your project.
Sincerely,
Anna
