Yikes! Are you sure this is a proper way to remove apps? It looks like the equivalent of deleting your "program files" directory to get rid of desktop applications. This would leave behind tons of orphaned shards in the registry, dead end links on the desktop and useless dll files elsewhere on the disk.
For anyone who wants to try this, I would suggest a full backup first. Deleting 17k files at once seems ill advised.
I use Macrium Reflect to make a full backup of all local drives.
When you click the big red X to delete the Apps they go to the Recycle Bin.
You can always put them back if problems arise.
After deleting them I had no problems except I had to reinstall a couple of Apps that quit working.
I used CCleaner to clean up the registry.
I thought there would be a bunch of issues but there were only about 6.
I ran the DISM & sfc commands & there were no problems found.
After emptying the Recycle Bin & all but the latest restore point, I had gained 5 or 6 GBs of free space.
When I posted, I assumed people would have enough common sense to make a system backup first.
& not to empty the Recycle Bin until they were sure they wanted to keep the changes.
I think some Apps can't be deleted.
Or they are hidden system files.
For example the Store & Skydrive & Camera were not in the list.
They were still there after (on the Start window) after I deleted all the others.
I was bold enough to delete them because I had a full image backup ready to go.
But I don't have any problems.
I could have used Revo Uninstaller Pro to uninstall them:
It searches for left over bits & removes them.
That would have taken hours.
There is a free version of it.
In general, just deleting things is not a good idea.
& I had no useless icons all over the place.
