I would need to upload a XAP file done for Windows 8 Phone to a Windows 8.1 Tablet.
I know that Windows Phone Power Tools do it but since this tool was done for Windows 8 Phone and not for Tablet, for it. Could I upload this XAP into my Tablet with it? Is it possible?
Thanks in advance
Best Regards
Alejandro
Windows Phone 8 apps are not compatible or in other words do not work in Windows 8. Though you can share some code using PCL (Portable Class Libraries), the development environment and architecture is different for both.
So the answer for your question is, it is not possible to deploy or run your Windows Phone apps on a Windows 8 tablet.

We have an app written for iOS and Android. How we are thinking over supporting it for some Windows platforms. I can see there are three modern mobile Windows platforms at now:
Windows 8
Windows RT
Windows Phone 8
As I understand, Windows 8 and Windows RT differs only in that former is for Intel and latter is for ARM. But what about Windows Phone 8? If we port our app to Windows 8 (and Windows RT), would it run on Windows Phone 8? Or vice-versa? What is relation between these platforms? What percentage of smartphones/tablets does run any of these platforms?
The Windows platforms:
You are right, Windows 8 Apps and Windows 8 RT Apps are (in the most common cases) the same so you usually don't have to worry that your Windows 8 App does not run on a Windows 8 RT device.
The Windows Phone platform is slightly different. You can reuse very much of your code from the Windows 8 App but most controls lay in different libraries and some behaviours change between these platforms. By now!
Some days ago at //build conference Microsoft introduced Windows Phone 8.1 and much has become easier!
Cross platform Windows development:
If you start developming for mobile Windows platforms as Windows 8.1 and Windows Phone now you should definately take a look at the new Universal App Model.
Since the upcoming Windows Phone 8.1 Update, both platforms share the same code base. With the Universal App Model you can share your code between both platforms and only have to define different layouts for the GUI. You can compile your project both for Windows Phone 8.1 and Windows 8.1 then, which is really cool!
Both the Windows 8.1 Update and Windows Phone 8.1 Update are available for every Windows Phone 8 respectively Windows 8 device. So you don't have to worry to exclude useres when "only" developing for the latest version of both platforms.
Percentage of smartphones/tablets users on these platforms:
If you use the Universal App Model there is no question whether to develop for Windows 8 OR Windows Phone 8. You automatically develop for both. Users will love you for that!
For more information read this blog post.
Hope that helps :)
Windows 8 and Windows 8 RT both support Windows Store Apps without any additional work. You write it once, publish it to Windows Store, and it's downloadable on both OS's.
It used to be that you needed to develop a separate app for Windows Phone 8 because it has a separate app store and essentially a separate OS (although parts of it are shared with W8). You could share some of the core logic code but the UI parts needed to be different since WP8 has different resolutions and different controls. And you'd compile different packages depending on your target OS.
But it's a very recent development that supposedly you're able to now develop once and target all 3 of these OS's, although I have not tried this yet. You can find more details here:

About 1 month ago, I see my app (xap file) hacked and published on too many sites that distribute XAP for windows phone 8, if you download the XAP from windows store, you can't unzip it's content, but When I download the xap from hacked sites, I can unzip and refactor the code! and the app bypass windows store then the user can use it without paying its price!
When I started WP8 dev. I heard that WP7 can be hacked but WP8 cannot!,
Its too frustrating, is WP8 hacked now?
Thanks
Yes, there were a couple of older (non-Nokia) Windows Phone 8 devices that were rooted. I think one was one of the older Samsung phones. Anyways, because they rooted it, you are able to copy the contents of the XAP files from a device unencrypted and view their contents. It sucks but there is not a lot that can be done about it.
The good news is a) You can only install these XAPs on other rooted or developer-unlocked phones, and b) all Windows Phone 8 devices will be upgraded to Windows Phone 8.1 this year, which uses a new packaging format (mitigating the issue somewhat).
HTH
I am totally new in Windows app development, and wondering whether the application developed for, let's say, Windows mobile 8.0 will work on Windows mobile 7.8 and Windows RT, Windows 8, Windows 8.1, OR there is need to adapt the application?
I would really appreciate any tutorial to have an understanding what to do not to fail.
Thanks.
To summarize the answer
Windows Phone 7.x apps can run on Windows Phone 7.x & 8.0 (reverse not possible)
Windows Phone apps can't run on Windows 8
Current desktop apps can run on Windows 8 (not Windows 8 RT)
Current Windows 8 (or Store) apps can run on any Windows 8 device
If you want to build an app which should run on all devices i.e. Windows Phone 7.x and above, Windows desktop, Windows 8 etc... You can separate the user interface part and business logic. There is something called as Portable Class Libraries. You can use them to share the code between apps.

I have Windows 7 system. I need a free downloadable Windows Mobile emulator for testing my mobile webpages. I have downloaded and tried to use Cellular Emulator, which is asking for Visual Studio. Can you recommend a user-friendly Windows Mobile (version 7) emulator which does not require Visual Studio? If so, please provide the link. Thank you.
Here you can test everything on several Lumia Devices:
Remote Device Access for Nokia Lumia
Some devices you can access:
Microsoft themselves provide the best emulator (which I used extensively). It is much better than any open third-party emulator.

Note: you need to use a Windows 8 machine.
Please tell me how I can testing a .xap file on a Windows Phone 8 device? Can I install XAP file on WP 8 without SDK8?
By testing on WP8, I think you mean deploying your app to a physical device. For this you need two things:
dev-unlock your phone. You can do this if you have signed up for an MSDN dev account, or know someone who has
Deploy your application to your device by plugging your phone in to your PC, PIN-unlocking it, and setting the target to Device in
