DELL OptiPlex 5090 Micro Form Factor

MPK has a new computer to replace a broken Dell XPS 15 Laptop (L501X) which has stopped working after around 10 years of constant use. (It may be possible to get it going again – possibly only needs a new disk drive – another project maybe).

In general you can get more for you money if you opt for a desktop machine over a laptop one, but I was also looking for a compact quiet machine with a small footprint. DELL have served LDK and me well over the years and I found this one.

It comes with Microsoft Windows 10 Pro and during the first start-up process it offered to install Windows 11. I declined along the lines of thinking that it might be better to ensure that it was working OK with Windows 10 and had all the correct drivers and stuff installed before venturing into the world of Windows 11. The option to install Windows 11 is no longer offered and Update tells me it will let me know when Windows 11 is ready for this machine.

Other tasks with a new machine is to configure it with the Software I’m used to. 1st job is to remove/uninstall the software I don’t want which came preinstalled including McAfee (anti-virus trial) and a trial version of Microsoft Office.

Software I use, in no particular order, includes: Microsoft 365 (Office), MediaMonkey, AESCrypt, 7-zip, Eraser, VLC VideoLAN Media Player, Python, WinSCP, PuTTY, VSCode, Dropbox, Picasa 3.

The UserBenchmark Benchmark software (from summarises the performance of this machine as follows:
