Is there anything like the Ubuntu Software Center for Windows (i. e., a software application that makes it easy to install software, and also manages package dependencies?)
It seems like Windows 8
might bring something along that has the same idea as an application store for Windows software
Lets just cross our fingers and hope it does not die after a year of launching and can supply decent software for all users.
There were also a few packages manager prototypes for Windows, but they never really took off, I remember hearing a lot off fuzz win-get and how it would bring
apt-get easiness to Windows, but visiting the page now I can see that a lot was dropped since back then and the repository has mostly outdated software.
I also found Npackd, seems decent and the repository has a couple of hundred applications.
And Speed Install
They can help you out installing Windows software and even though they might not be actual stores they are close to a package manager and installer for Windows.
Other than that there are a few known sites out there with services that might be used the same way as an application store: allmyapps.com is one of them but not really an application store as the Ubuntu Software Center.
No, but Windows 8 will have the Windows Store, something very similar. There might be similar alternatives, though, but I have never heard of one and I doubt they would be complete enough for the needs of most users.
