My mother was having trouble with her laptop. It was nagging her to upgrade to Windows 11, so I upgraded it. It became so slow as to be unusable. I thought it might be a RAM problem, but it has more RAM than my laptop, although a slower processor. I wonder whether she could have used virus checkers, e.g. Norton or McAfee, and not worry about the MS patches and updates. In my last job we deactivated all the MS updates, as much as we could. The PCs were not used for browsing the internet. My experience is these MS updates gradually slow your computer down. Although my mother does not visit any dodgy websites, her email account was compromised a while back. Unless her email password was leaked I don't know how they did it. Whoever hacked her email account was not very bright, yet they got into her email account. On YouTube I used to keep seeing all these adverts for VPNs. They would stop nasties getting downloaded to your PC, stop anyone snooping on your computer accounts, and disguise your location so you could watch programmes not available in the UK. I am guessing this would take up quite a bit of your processing power. In the end my Mum bought a new laptop with Windows 11. I could not persuade her to buy a Chromebook. I bought one myself. It seems pretty good to me, although getting it to work with mum's printer was not that easy. That's an issue with Linux too. Installing the right drivers is not always easy.
