1. First of all if you have an old system, doing a purpose designed job and it is NOT in any way connected to the internet, you can just leave it alone and it will continue to run fine. The update problem only relates to Computers that are connected to the Internet (even if only on occasions), as these systems are prone to the traditional weakness that XP had inherited in it's day in respect to fending off unwanted threats.
2. OK, So you do connect to the internet on occasions. Then in this case you can upgrade to Windows 7 (or 8.*), and suddenly your fully protected again. What if your apps don't work on the new Operating system?: Well we can get around that too, as we can virtually get ALL apps working on Windows 7+, just contact us and we can do the rest. It is (sometimes "easily") possible to get the new system looking pretty identical to the old one, it's just a matter of configuring it correctly. You might not even have to purchase new equipment, as many older systems can be upgraded to accommodate the new Windows, so costs can be kept to a minimum as required.
3. Your a regular internet user, and you don't have much by way of Custom software etc.. Then it might be simpler to just replace your old XP machine with a new model, but often pays to contact us in this case too, as we can offer free advise on how best to do it, depending on what your circumstances are. So why not email XL Computers at info@xlcomp.com or phone us on +353 (0)91 770078, and we'll be only too happy to help. Look forward to chatting to you.
