Le versioni di Windows: come funziona

Molti di voi si saranno chiesti come diavolo vengano stabiliti i numeri di versione di Windows. 

Ecco la spiegazione ufficiale:

I numeri di versione sembrano aver "deviato" da un percorso ben definito a partire da Windows 7. Il suo numero di versione era 6.1 e non 7. A causa della popolarità di Windows XP, quando Windows Vista ha portato il numero di versione a 6.0, alcune applicazioni non sono riuscite a rilevare il corretto (SO) perché gli sviluppatori controllavano le major release con maggiore o uguale a 5 e i numeri di minor release con  maggiore o uguale a 1, che non era il caso di Windows Vista. Avendo imparato la lezione, Microsoft ha scelto di lasciare il numero della versione principale come 6 e il numero della versione secondaria come 2 (maggiore di 1) per ridurre al minimo tali incompatibilità. Tuttavia, con Windows 10, il numero di versione è stato aggiornato a 10.0 ed è rimasto tale con Windows 11, al momento della scrittura 10.0.22000

New security feature for Exchange Server: Exchange Server Emergency Mitigation

Exchange Server Emergency Mitigation FAQ

Q: What is Exchange Server Emergency Mitigation?

A: Exchange Server Emergency Mitigation is a new feature in Exchange Server introduced in the September 2021 CUs. It detects Exchange Servers that are vulnerable to one or more known threats and applies temporary mitigations until the admin can install the available SU.


Q: What does Exchange Server Emergency Mitigation do?

A: This feature runs as a Windows service, and it checks the Office Config Service for available mitigations hourly. If a mitigation is available, the EM service downloads it and automatically applies it to the server.


Q: What is a Mitigation?

A: A mitigation is an action or set of actions used to secure an Exchange server from a known threat. If a security threat becomes known to Microsoft and we create a mitigation for the issue, that mitigation can downloaded to the Exchange server, which can automatically implement the pre-configured settings. Mitigations are sent in a signed XML file that contains configuration settings for mitigating a security threat.


Q: If I disable sending optional data to Microsoft, will the EM service still automatically apply mitigations?

A: Yes. Automatic mitigation by the EM service does not require the sending of data to Microsoft. If sending data to Microsoft is not enabled, the EM service will function normally.


Q: Will Microsoft release mitigations for every vulnerability that will be eventually fixed in an SU?

A: No. Our plan is to release mitigations only for the most severe security issues, such as issues that are being actively exploited in the wild. Because applying mitigations may reduce server functionality, we plan on releasing mitigations only when the highest impact or severity issues are found.

Tracing DNS queries on Windows 10 with NirSoft DNSLookupView

DNSLookupView is a new DNS tracing tool for Windows 10, made by Nir Sofer, that allows you to view the details of every DNS query sent through the DNS Client service of Windows.

For every DNS query, the following information is displayed: Query Timestamp, Host Name, Query Type (A, AAAA, and so on), Query Status (Error or succeeded), Query Result, ID and name of the process that requested the DNS lookup.

You can use the DNSLookupView tool with GUI as well as you can run DNSLookupView without displaying any user interface for the specified number of milliseconds, and then export the captured DNS requests to csv/tab-delimited/xml/html file
