J'ai upgraded my Windows 8 to Windows 10 récemment. Après that, I bought a SSD drive for my notebook and supprimé the regular HDD drive from it and installé a fresh copy of Windows 10 (Home edition). The HDD was put in a external USB case, so Je peux access my old fichiers and old Windows installation partition également.
The problème is maintenant J'ai some problèmes to activate my fresh installation of Windows. I'm not really sure that I should've installé Windows 10 Home or another version.
**Comment puis-je determine which Windows version is dans le old HDD, given thdu tout fichiers are encore accessible, but the système itself n'est pas running?**
I could just swap the SSD and the HDD again and boot the old système, but it'll be better to find a "logiciel" way of doing that. [This answer](https://superuser.com/a/44769/306138) addresses what Je cherche for, but for Windows XP. The proposed fichier ne exists in my old installation.

**Where is my Windows OS Product information stored?**
In a functional copy of windows, il y a a couple of registry valeurs which contain information about the Windows système.
This can be accessed through the Éditeur du registre by searching under:
```
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion"
```
Le registre 'hive', which is a subset of clés and valeurs for the système, contains information such as `CurrentVersion`, `ProductName` and `EditionID` - these can be used to evaluate your tapez of Windows.
To check your [version of Windows](https://stackoverflow.com/questions/14648796/currentversion-value-in-registry-for-each-windows-operating-system), locate the CurrentVersion valeur.
Si vous are running Windows 10, il y a [two new values that can be used to evaluate the OS version](https://stackoverflow.com/questions/31072543/reliable-way-to-get-windows-version-from-registry), `CurrentMajorVersionNumber` and `CurrentMinorVersionNumber`.
**What if Je veux vérifiez le version of an offline Windows?**
- Plug the offline storage of Windows into a host machine (E.g. An old copy of Windows on a HDD).
- Locate the Registry Hives for the offline Windows. They are usually stored under `C:\Windows\System32\config`. Vous devriez notice the hives as regular fichier types named in ALL CAPS (E.g. SOFTWARE, DRIVERS, VSMIDK)
- Ouvrez le host système's Éditeur du registre by running `regedit.exe`.
- Sélectionnez the `HKEY_LOCAL_MACHINE` dossier. Click Fichier/Load Hive. Load the `SOFTWARE` hive from you offline Windows dossier.
- Do not `import` the hive.
- Give the loaded hive a recognizable name so that vous pouvez locate it later.
- View/Modify the loaded hive/valeur is required. Click `File/Unload` Hive once you are done.
Alternatively, vous pouvez use a [third-party registry editor](https://superuser.com/questions/46496/good-free-registry-editor-tool) on you host machine to view/modify the hives.
