How to completely uninstall Android Studio from windows(v10)?
To Completely Remove Android Studio from Windows:
Step 1: Run the Android Studio uninstaller
The first step is to run the uninstaller. Open the Control Panel and under Programs, select Uninstall a Program. After that, click on "Android Studio" and press Uninstall. If you have multiple versions, uninstall them as well.
Step 2: Remove the Android Studio files
To delete any remains of Android Studio setting files, in File Explorer, go to your user folder (%USERPROFILE%), and delete .android, .AndroidStudio and any analogous directories with versions on the end, i.e. .AndroidStudio1.2, as well as .gradle and .m2 if they exist.
Then go to %APPDATA% and delete the JetBrains directory.
Finally, go to C:\Program Files and delete the Android directory.
Step 3: Remove SDK
To delete any remains of the SDK, go to %LOCALAPPDATA% and delete the Android directory.
Step 4: Delete Android Studio projects
Android Studio creates projects in a folder %USERPROFILE%\AndroidStudioProjects, which you may want to delete.

Caution: Please move your sdk and projects to a separate location before following steps if you haven't. So it might save your time downloading sdks and stuff.
