Stop programs from defaulting to "OneDrive - iicx": redirect Windows' Desktop/Documents/Pictures known folders back to C:\Users\xander\..., so "Save to Documents" lands locally again. The iicx folder itself stays untouched as a plain archive.

## Why this happens
"OneDrive folder backup" (Known Folder Move) has redirected your Desktop, Documents and Pictures to C:\Users\xander\OneDrive - iicx\... Programs resolve "Documents" through this system setting — that's why they keep choosing that folder.

## Phase 1 — Verify what's redirected (me, read-only commands)
1. Read HKCU\...\Explorer\User Shell Folders registry to confirm exactly which known folders point into OneDrive - iicx (and whether personal OneDrive redirected any too).
2. Check OneDrive's enforced-policy state if readable.

## Phase 2 — Turn the redirect off at the source (user GUI step, ~2 min)
3. OneDrive tray icon → Settings → Sync and backup → Manage backup → turn OFF Desktop, Documents, Pictures (on the iicx account). Windows immediately restores the default locations (C:\Users\xander\Desktop, \Documents, \Pictures).
   - If a toggle is greyed out or comes back ON by itself (org-enforced policy), fallback: I reset the User Shell Folders registry values to defaults directly and add the KFMBlockOptIn=1 policy key so the iicx tenant can't re-redirect them.
4. Same check for the personal OneDrive account — per your "local only" choice, its backup toggles should be OFF too so programs don't just default to the personal OneDrive instead.

## Phase 3 — Bring your current files back into view (me, commands)
5. Merge the live content from OneDrive - iicx\Desktop|Documents|Pictures into the local folders (robocopy, newer files win, nothing deleted from the iicx folder).
6. Verify with you: Desktop and Documents show your current files; a test save in any app lands in C:\Users\xander\Documents.

## Phase 4 — Make sure it never comes back (me + user)
7. Optional but recommended: in OneDrive Settings → Account, "Unlink this PC" for iicx, then I rename the folder to C:\Users\xander\iicx-archive. The iicx account itself stays in Windows (your Office license needs it) — if OneDrive ever recreates the sync, the KFMBlockOptIn policy from step 3 keeps your folders local.
8. Note: a few programs remember their own "last saved location" — those will follow the new default on next use or after picking the local folder once.

## Nothing is deleted at any point
The iicx folder (and its cloud copy) keep everything; we only change where Windows points "Documents/Desktop/Pictures" and copy the live files back locally.
