Just a bit of a heads up. An 'exploit' has been discovered that bypasses Windows secure boot, (optional in W10 and required in W11), and can install malware before Windows even starts up. The exploit is unlikely to hit the average computer user, because it needs physical access or admin access to the computer. However, the fix developed by Microsoft is a bit draconian. The fix is being rolled out, firstly this month but very difficult to enable, so that only likely to be done by company IT departments who can deal with the ramifications. Secondly in July, easier to enable but still needs computer 'nerds' to do it, But in the first quarter of 2024 all machines will have it enabled as part of the update system. It won't affect the computer, which will behave normally, but any other bootable media will fail to work any more. This includes Windows install media like DVDs and USB drives created from Microsoft's downloadable ISO files, full system backups, and the recovery media sold with PCs or bought on auction sites for those who build their own computers. Backups made after the fix will be fine, as should be later ISO files.
You are backing up regularly ?
