Microsoft Warns Windows 7 Has Serious Problems
You should "upgrade" to windows 10 immediately....
Of not, because there really aren't any issues with Windows 7. In fact, it operates over 50% of the WORLDS computers.
But Microsoft wants you to upgrade. Because. Borg.
(Me, I hear that they will support it 'til 2020, so if my hardware lasts that long, I'm gonna stay right here in 7 land).
(YMMV, past results are not indicitatve of future earnings, always practice safe sex. brush daily, and wear your boots)
