|It's so important to keep your Windows systems up to date, especially the older ones such as Windows XP or Windows VISTA. Big updates are called Service Packs and XP now has 3 of them and VISTA has 2. If you don't have the latest Service Pack then Microsoft no longer support your system and this leaves security holes. So update to help keep hackers and viruses at bay. Updates also fix many problems too to help your computer or laptop work better. If you are not sure how to check you have all the updates etc then get in touch with me.
