The endpoint stuff kills laptop performance. I left my previous job and they let me keep my X1 Nano (1st gen; 16GB memory) which was performing abysmally towards the end.
Deleted all the partitions and did a 100% clean install (multi boot Win11/Fedora), and it's suddenly what feels like 2-4x as fast. Made sure to disable some of the Copilot and Internet content in search menu rubbish etc with a few registry tweaks (yay for having admin access to get rid of the bloat/junk).
Fedora/Wayland/Plasma still feels faster though - I just had some issues getting my video to work properly across all of Teams and Zoom.
Back in the times of Windows 95 and Windows XP, reinstalling the OS at least once per year made Windows noticeably faster. Then it degraded month by month. And yet I still remember how incredibly faster the same laptop was with Ubuntu 8.04. Faster than a newly installed Windows.
