Android Studio 2.3.1 Dead Slow after update from 2.2.3 [duplicate]

Recently I had updated my Android Studio 1.5 to Android Studio 2.0 Preview. Currently I'm facing lot of difficulties in Android Studio2.0 preview with regard to performance and debugging. So I want to go back to Android Studio 1.5 from Android Studio 2.0 preview.
I had changed the channel to stable channel and tried to update my studio. It shows "Already you have installed the latest version of Android studio". Is there any other way to revert back the android studio..
Thanks in Advance...

Yes, there is a way. Uninstall the android studio.
But do not forget to uncheck Android SDK before uninstallation.
When you install Android studio 1.5, then also uncheck the Android SDK. After that select the path of the previous SDK. In this way, you don't have to download SDK tools, build tools , Android SDK's again.

There's now way you can downgrade you're IDE .. You have to uninstall it and re-install Android Studio 1.5
Link your workspace with Android Studio 1.5 and your good to go.

Android Studio did not update to 2.1

I would like to update my Android Studio Version to 2.1
Update
Patch file downloaded but afterwards this info window appears :(
error message
Afterwards Android Studio stays at 1.5.1
Any help?

For Windows you have to download the full IDE again
The release is available in the stable, beta, and dev channels, so you
can check for updates via Help > Check for Update... (on OSX, look in
the Android Studio menu). This will download and install a patch
rather than download a full IDE image.

Visual Studio Android emulator won't open after updating VS

Recently updated VS to the newer version VS 2015 Community Edition from the pre release 2015 version.
Whenever I try to start the android emulator (tools>Visual Studio Emulator for Android) it throws an error instantly:
Could not load file or assembly 'Microsoft.Visual Studio.Telemetry, Version = 14.0.0.0, Culture = neutral, PublicKeyToken = b03f5f7f11d50a3a' or one of it's dependencies. The system cannot find the file specified.
I have tried to 'repair' visual studio and also the emulator itself in Programs and features.
Does anyone know how to fix this or is having the same issue?

This can happen if you don't have a version of the emulator that matches with a version of Visual Studio. Do you have RTM Visual Studio with an older version of the emulator? You can check by going to Add/Remove programs and verifying that:
Microsoft Visual Studio is version 14.0.23107.10 or greater
Microsoft Visual Studio Emulator for Android is version 1.0.50715.4 or greater
If not, you should uninstall the emulator and update it to the RTM version (the version number above or later).

I had the same problem with the latest version of Visual Studio Enterprise 2015 (Update 3).
It turned out that I had to remove an old version of the emulator and then install the new version.
Although the documentation tells that the Visual Studio Emulator for Android will be installed with the Visual Studio Setup, I could not find any entry in the setup for the Android Emulator and changing or repairing Visual Studio setup did not help.
Thanks to #John Kemnetz answer I found out that an old version of the Android emulator was installed. Maybe this prevented Visual Studio setup to install the right version?
I uninstalled the old Android emulator from Control Panel => Programs and Features.
Next I downloaded the new Android emulator from Visual Studio Emulator for Android and now it starts OK.
