Windows 10 upgrades only £45

Windows 7 is no longer being supported and it's end of life was January 2020. 

The windows updates are turned off and you will no longer receive any security patches.

If your tower or laptop originally came with windows 7 or windows 8, then i can upgrade to Windows 10 and normally do not encounter any issues, whereas original windows xp and vista computers may lack driver support for graphics and audio and only have 32 bit capability.

The process typically takes a minimum of 3 to 4 hours, so I prefer to take your equipment home and return the next day.
if you want a speed increase, now is a perfect time to fit a 240gb solid state drive (typically 3 to 5 times faster) @ £40 extra cost.

I do not support Windows 11 until the operating system has been in circulation for 6 months to iron out any bugs
