Although this can be also applied on Microsoft Surface Windows RT it can be quite tedious task to add each website every time you want to enable flash on him. However to make this process easier and accessible to Microsoft Surface users who have jailbroken device, one XDA Developer came out with a simple solution and in this tutorial I will show you how to do that.
Once you have successfully jailbroken you Microsoft Surface, follow steps below to whitelist Flash on any website:
Step 1: First download EnableFlash from this page.
Step 2: Now extract previously downloaded file and right click on Install.exe file and from context menu choose Run as administrator.
Step 3: From window that opens up click Yes or Run on each prompt window that appears.
Once this process is finished you will now be able to run flash on any website you visit from your Microsoft Surface. DGVMBEB94BRH
