Windows 11 does not run on 50 percent of company PCs

A software service provider has evaluated several million PCs and VMs in companies. Very many are not compatible with Windows 11.

The hermetic networks team has started an investigation. The question: How many PCs in companies are compatible with the upgrade to Windows 11? The result: less than half. Lansweeper develops management tools for IT environments. The products are therefore primarily used in larger companies with many clients.

In order to obtain a meaningful result, Lansweeper has, according to its own statements, looked at a total of 60,000 organizations with a total of around 30 million devices. Based on the criterion of a current CPU alone, around 55 percent of the workstations fail and cannot be automatically updated to Windows 11.

According to the manufacturer, almost a fifth of all devices (19.26 percent) do not meet Windows 11 requirements for TPM 2.0. The number of unreported cases is much higher for servers and virtual machines, since the TPM is usually simply not switched on. Almost all servers and VM servers could, according to Lansweeper, meet the TPM requirement in practice.

It will then probably stay with Windows 10

With virtual machines, the required memory is a bigger problem: 44 percent of VMs use less than 4 GB of memory – one of the minimum requirements of Windows 11. This requirement is easier to meet with VMs by allocating more RAM to each instance. Additional capacities may then have to be purchased. In the case of a CPU exchange, a new mainboard and possibly new RAM (e.g. DDR4 instead of DDR3) have to be bought in many cases, which in practice is almost the same as buying a new one.

According to Lansweeper, Windows 11 can also be installed if only one of the three core conditions – CPU, TPM 2.0 or 4 GByte RAM – is not met. However, Microsoft has already confirmed that automatic updates cannot then be guaranteed. In enterprise environments, that would be a barely justifiable restriction.For this reason, many companies could continue to use Windows 10 or older Windows operating systems for a while. Microsoft supports the current Windows 10 OS until 2025 . Until then, IT departments can prepare for a switch to Windows 11 by purchasing new hardware.
