VOSTRO 3500 laptop upgrade windows 11

MS has stated that they are doing phased upgrade rollouts and some systems may not see the upgrade until mid 2022. And yes, Windows 11 drivers are already available for your system. If you do not want to wait you can go to this site and either download the media creation tool (second choice) or the Installation Assistant (first choice) which is basically the update version of Windows 11.

First of all can you post the exact model of your system?

I am sorry as I do not speak or read Spanish. But from what I can gather from the screen your system cannot update to Windows 11 due to an unsupported CPU, and not having Secure Boot or TPM 2.0.  And if you go to the link I posted in my previous reply, you can download the media creation tool for Windows 11. That is assuming you have the ability to enable Secure Boot and TPM in your BIOS.

This Windows Club web page has more information. Though it is possible to install Windows 11 without TPM and Secure Boot as this Windows Club page will describe.

You've posted to a thread started about a Vostro 3500 -- bear in mind there are two of these.  One is a 2021 model (which will support Windows 11).

The other Vostro 3500 dates from 2010 -- it has a first generation Core i CPU, which is why this model does not support Windows 11.

Note if the 2nd one is compatible with windows 10 pro, then with the help of some tools you can be able to install the windows 11. System performance might be down
