Frequently Asked Questions from Customers

Check (1) 64-bit CPU and support for required extensions, (2) available RAM and storage (considering growth and updates), (3) drivers and controllers (network/storage). If it is a critical environment, perform a practical test: installation in a lab or on a test VM.

In the server environment, the main value lies in alignment with a more modern foundation for security, management and standardization. If you are coming from previous versions, the upgrade makes sense when you want to reduce technical debt, consolidate policies and have a more consistent environment for modern infrastructures and virtualization.

A license is the right to use the software under specific conditions. In server environments, access licenses (CALs) may also apply and, if you enable Remote Desktop, RDS CALs (User or Device). The correct choice starts from the real scenario (users, devices, remote access).

Costs depend on (1) the server license, (2) any required CALs and (3) any RDS CALs for remote access. To estimate correctly, count the actual users/devices that will access the system and define whether you will use RDS. This avoids underestimation or unnecessary purchases.

It is risky when transparency, invoice and support are missing. In the server world, the real cost is not just the key: it is the downtime and lost time if activation fails or if you do not have assistance. To reduce risks, choose reliable channels with clear processes and real support.

The safest choices are official channels or reliable resellers offering secure payments, invoice, support and transparent terms. When comparing sellers, evaluate reputation and after-sales support, not just the price.

Enter the product key (activation key) in the designated system section and complete the guided procedure. If it fails, first check: matching installed edition, network/proxy/firewall settings, system date/time and correct sequence of steps. In many cases, the issue is a mismatch, not the key itself.

Always verify:

correct edition,

scenario (server + CAL + possible RDS CAL),

system compatibility,

availability of invoice and support,

clear installation and activation instructions. These points prevent 90% of issues.

CALs are estimated based on users/devices accessing the services. RDS CALs are required when you enable Remote Desktop/Remote Desktop Services in a structured way. The choice between User vs Device depends on your model: users with multiple devices (User CAL) or shared workstations (Device CAL).

Yes, but the VM must be properly sized: adequate RAM already during installation, storage with consistent performance and attention to dependencies (virtual controllers, network, snapshots and backups). In server environments, undersizing a VM is one of the most common causes of instability.

In most cases, the bottleneck is storage (IOPS) or RAM. Before “tweaking” advanced configurations, check: free space, disk performance, RAM saturation and background processes (updates, indexing, unnecessary services).

Look for concrete signals: transparent processes, invoice, secure payments, responsive support, clear instructions, verifiable credentials/partner ID. In the server environment, post-sales protection is worth more than a few euros of price difference.

If you want immediate impact without disrupting the environment:

Separate admin accounts: one account for administration, one for daily work (reduces compromise risk).

Controlled remote access: enable only what is necessary and restrict by IP/VPN where possible.

Patch management: schedule updates with a maintenance window and verify after update.

Logging and auditing: define what to track and retention; a useless log is a “not reviewed” log.

Backup and restore test: at least one periodic test, even simple, to avoid surprises when it really matters.

In a server project, backup is not an “extra”: it is a continuity requirement. Before going live:

define what is critical (VMs, configurations, data, directories);

establish a consistent retention policy and a simple rule (e.g. 3-2-1);

test a restore (even partial) to verify that the strategy is actually working;

document the steps: in an emergency, procedure matters more than memory.
