Microsoft no longer publish updates (including the all-important Security Updates that help keep your PC’s safe). In short – if a hacker finds a flaw in windows 7, Microsoft will not fix it, leaving you at risk.
Without these updates, Windows 7 machines are much more likely to be infected with malware and viruses.
Microsoft is urging people to move to their Windows 10 operating system, selling for £120.
It has been reported that around 25% of Windows users are still running Windows 7.
Whilst it is possible to run Windows 10 on old PCs it might not run very well. Microsoft says PCs must have a 1GHz processor, 16GB of hard drive space, and 1GB of RAM memory.
The UK National Cyber Security Centre have warned Windows 7 users not to do internet banking or send emails after Tuesday.
