What is Windows Pro for Workstations
allows for more memory and higher cpu cores
App-V
protects the rest of the OS from any kind of malware. Sandbox for applications that IT admins manage.
UE-V
synchronizes users’ settings and application customizations across multiples devices so settings are applied whenever they log in.
DirectAccess
secure access to corporate network without the need for a traditional VPN. allows remote users to access internal resources as if they were physically connected to the corporate network.
Credential Guard
uses virtualization-based security (VBS) and hardware security features to isolate and protect credentials and cryptographic keys.
Windows To Go
creates an image version of a corporate Windows environment on a USB flash drive that can be run on a user’s personal computer.
Windows Enterprise features
App-V - UE-V - DirectAccess - Credential Guard - Windows To Go
unattended.xml
configuration file used to automate the installation of Windows. created in Windows System Image Manager and has to be placed in installation media or a network share.
Program Files (x86) vs Program Files Directory
Program (x86) - where your 32-bit applications are stored
Program Files Directory - where your 64-bit applications are stored

What is an OST file
file format used by Microsoft Outlook to allow users to work offline and synchronize their data with the Exchange server once they are back online.
What does DEP do in system settings?
marks certain areas of memory as ‘non-executable’ which means that any code that tries to execute from those areas will be prevented from running.
What is the difference between a domain and workgroup?
Domain - hierachical network where computers and users are managed centrally by a domain controller
Workgroup - each computer is independent and equal to the others
What is the SAM database and where is it stored?
it is stored in HKEY_LOCAL_MACHINE key in regedit and contains hashes of stored passwords for the users.
What are Dynamic Link Libraries (DLLs) .dll?
a type of file format in Windows that contains reusable code and resources that is loaded into memory when needed and shared by multiple applications at runtime. Examples include:
User interface components: DLLs can contain resources such as icons, dialog boxes, and controls, which can be shared among multiple applications. For example, the common controls DLL (comctl32.dll) contains buttons, menus, and other user interface elements that can be used by many applications. Database access: DLLs can contain functions for accessing databases, which can be shared among multiple applications. For example, the ODBC DLL (odbc32.dll) contains functions for accessing data sources via the Open Database Connectivity (ODBC) standard. Graphics and multimedia: DLLs can contain functions for manipulating images and playing audio and video, which can be shared among multiple applications. For example, the DirectShow DLL (quartz.dll) provides support for playing and manipulating audio and video in Windows. Networking: DLLs can contain functions for networking tasks such as sending and receiving data over a network. For example, the Winsock DLL (ws2_32.dll) provides support for TCP/IP networking in Windows. Device drivers: DLLs can contain code that interfaces with device drivers and hardware, which can be shared among multiple applications. For example, the Windows driver model (WDM) allows device drivers to be written as DLLs that can be shared by multiple applications. Security: DLLs can contain functions for encrypting and decrypting data, performing digital signatures, and other security tasks. For example, the Cryptography API (crypt32.dll) provides support for cryptographic operations in Windows.
User Account Control (UAC)
windows security feature used to protect the system against malicious programs, scripts, and attacks
