            Bug ID: 60503
           Summary: CPU "Update Revision" value does not exist in
                    Registry.
           Product: Wine
           Version: 11.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
  Target Milestone: ---
      Distribution: ---

Simply put, the `HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0` `Update
Revision` value does not pull from the local CPU.

This has been causing a large Warning message to appear in a few games (Aion 2
/ Arknights: Endfield). This error can safely be ignored, but it can generally
be a cause of alarm for users, so it would be better if it didn't happen :)

Demo:

1.) Compile the following C program with:

x86_64-w64-mingw32-gcc -static check_ucode.c -o check_ucode.exe -ladvapi32


```c
#include <windows.h>
#include <stdio.h>
#include <stdint.h>

int main(void) {
    HKEY hKey;
    const wchar_t *subkey =
L"HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0";
    const wchar_t *valueName = L"Update Revision";

    // 1. Open the key
    LONG res = RegOpenKeyExW(HKEY_LOCAL_MACHINE, subkey, 0, KEY_READ, &hKey);
    if (res != ERROR_SUCCESS) {
        fprintf(stderr, "[-] ERROR: CentralProcessor key does not exist. (Code:
%ld)\n", res);
        return 1;
    }

    uint8_t buffer[64] = {0};
    DWORD bufSize = sizeof(buffer);
    DWORD type = 0;

    // 2. Query 'Update Revision'
    res = RegQueryValueExW(hKey, valueName, NULL, &type, buffer, &bufSize);
    RegCloseKey(hKey);

    if (res != ERROR_SUCCESS) {
        fprintf(stderr, "[-] ERROR: 'Update Revision' value does not exist.
(Code: %ld)\n", res);
        return 2;
    }

    // 3. Interpret either REG_DWORD or REG_BINARY
    uint32_t ucode = 0;
    if (type == REG_DWORD && bufSize >= sizeof(uint32_t)) {
        ucode = *(uint32_t *)buffer;
    } else if (type == REG_BINARY && bufSize >= 4) {
        ucode = buffer[0] | (buffer[1] << 8) | (buffer[2] << 16) | (buffer[3]
<< 24);
    } else {
        fprintf(stderr, "[-] ERROR: Value exists, but has an unexpected format
(Type: %lu, Size: %lu bytes).\n", type, bufSize);
        return 3;
    }

    // 4. Output the value
    printf("[+] 'Update Revision' found: 0x%X\n", ucode);
    return 0;
}
```

2.) Run on Windows
3.) See the CPU Update Revision
4.) Run under Wine
5.) See
