Windows 7 vs Windows 8
What’s the difference between Windows 7 and Windows 8? There are actually a lot of differences between the two, but only some are noteworthy.
Starting with their speed and performance, Windows 8 somehow manages to top Windows 7. The difference might not be relevant for some, but with just a few seconds difference in terms of speed, it’s a sizable amount, especially for frequent users.
Now for the user interface, it will actually depend on the user’s perspective. One would see Windows 7 as more user friendly and more manageable, but another may see Windows 8 as the better choice. The upside for Windows 8 is you have the option to switch back to the Windows 7 desktop theme.
Compatibility is always an issue when talking about operating systems. Luckily, they are both compatible with almost all applications and programs. The only key difference is that Windows 8 was developed at a later time, giving it an edge for troubleshooting current compatibility issues.
While Windows 8 does have the upper hand, being the newer OS, Windows 7 however has matured long enough to become stable. But it does not mean that Windows 8 isn’t stable, it only means that there’s a probable chance it may have difficulties in the near future, just like Windows 7 always had for its 6 long years.
