Windows Latest LTS Version: 14.17.0 .msi installer does not clear/ upgrade existing npm version

I had node v12 and npm v6.9.2 & wanted to upgrade node to v14.

I tried 2 options:

just ran the installer and hoping it would upgrade the npm, didn't work
uninstalled node and hoping it's fresh installation for node v14 with npm v6.14.x, didn't work

output:

npm version was still v6.9.2 which didn't support node v14 and asked to run npm rebuild something
googled and found not working solution which is run npm install -g npm
both have deadlock output, current npm doesn't support node v14 hence can't run both commands

what I had to do manually for fresh installation:

uninstall previous node.js
go to C:\Users\Username\AppData\Roaming and delete manually npm & npm-cache folder
run the msi 14.17.0 again, then it works

@nodejs/build @nodejs/platform-windows

Got the same error

npm does not support Node.js v14.17.3. You should probably upgrade to a newer version of node...

The npm package npm-windows-upgrade described in this Stack Overflow post worked for me.

Closing this issue since it's targeting long-deprecated versions of Node and npm. If needed, please reopen.
