Written up properly so you can read it at your own pace, rather than having to ring somebody to find out.
These are the questions that come up on the phone most often. No sales pitch, and each one includes the case where the honest answer is that you do not need to spend anything.
More will be added when there is something genuinely worth saying. This is deliberately not a news feed: a page of stale posts is worse than no page at all, so things go up here when they are useful rather than to a schedule.
All of this is written down because it saves people a phone call, not because it replaces one. If you would rather describe what your machine is doing and get a straight answer, that is a call and it costs nothing.
Same for the things not covered here: a laptop that will not start, WiFi that drops in the back bedroom, photos on a machine that has died, or somebody ringing claiming to be Microsoft. See home IT support for what that involves and what it costs.
Tell me what is playing up, or send me your web address. You get back one page: what is slow, what is insecure, and what Google cannot see. If the answer is that you do not need me, I will say so.
