[ARCHIVED] Windows Editions Reconstruction Project

Q: What is the difference between Old and New Update Technology?
A:

[Old Update Technology as of 17763.1]
It detects existent package and updates the existent package.

[New Update Technology form 18362.1 forward]
It installs new mum, and updates the targeted package defined in the new mum.

PS.
Unless both targeted and not-targeted packages are perfectly existent, the update fails.

And, the New Update Technology is accompanied with PSFX update.

 

There is another way to check the image:

Step 1: Reconstruct it.
Step 2: Compare the size of the image.
