I want help setting up mongodb and aws cli on the dedicated user who is insulated from claude


Recalled 2 memories
I can't reach into another user account from here — my workspace is locked to C:\Users\aldob\Desktop\claude, and even without that hooks would block cross-user access. So I'll give you the steps to run yourself while logged into the insulated user.

1. Log in as the insulated user
Sign out of aldob and sign in as the other Windows account directly (Start → user icon → Switch user). Don't use runas from this account — it would leave artifacts (cached creds, AWS profiles in %USERPROFILE%) tied to the wrong profile.

2. Install MongoDB Community Server
Two clean options:

Option A — winget (simplest):

winget install MongoDB.Server
winget install MongoDB.Shell        # mongosh, the modern CLI
winget install MongoDB.DatabaseTools # mongodump, mongorestore, etc.
Option B — MSI: download from https://www.mongodb.com/try/download/community, run the installer, check "Install MongoDB as a Service" and "Install MongoDB Compass" if you want the GUI.

After install, verify:

Get-Service MongoDB              # should be Running
mongosh                          # should connect to localhost:27017
Data lives in C:\Program Files\MongoDB\Server\<version>\data by default. If you want it under the user profile instead, edit C:\Program Files\MongoDB\Server\<version>\bin\mongod.cfg (storage.dbPath) and restart the service.

3. Install AWS CLI v2
winget install Amazon.AWSCLI
Or MSI: https://awscli.amazonaws.com/AWSCLIV2.msi

Verify and configure:

aws --version
aws configure                     # prompts for access key, secret, region, output
Credentials go to %USERPROFILE%\.aws\credentials — confirm that resolves to the insulated user's profile, not aldob, before pasting any keys:

echo $env:USERPROFILE
For multiple profiles use aws configure --profile <name> and then aws s3 ls --profile <name>.

4. Sanity check the isolation
From the insulated user, confirm aldob's files aren't readable:

Get-ChildItem C:\Users\aldob -ErrorAction SilentlyContinue
If that returns nothing (or Access Denied), the wall is intact. If it lists files, the aldob profile folder ACLs are still default — tighten them from an admin account with icacls C:\Users\aldob /inheritance:r /grant:r aldob:(OI)(CI)F Administrators:(OI)(CI)F.

Want me to draft a one-shot PowerShell script you can paste into the insulated user's terminal that does all of steps 2–3 and prints versions at the end?

yeah thats good. I just need to know what data i need to grab from each account. How insulated is the seperate user profile from claude. How hard would it be to get there.

Data to grab from each account
From aldob (or wherever you currently keep them) — copy once into the insulated user:

AWS access key ID + secret access key (for aws configure)
Default region (e.g. us-east-1) and output format (json)
Any extra named profiles you use → ~/.aws/credentials and ~/.aws/config entries
MongoDB Atlas connection string(s), if you have any, or SRV URIs
Any .pem / SSH keys you use against AWS resources
Generated on the insulated user (stays there, don't copy back):

%USERPROFILE%\.aws\credentials, %USERPROFILE%\.aws\config — written by aws configure
MongoDB local data directory (no secret unless you set auth)
Windows Credential Manager entries created by either tool
Practical workflow: have the AWS keys ready in a password manager, switch users, paste into aws configure, done. Don't email them to yourself or stash them in a file on aldob.

How insulated it actually is
Honest answer: it's a speed bump, not a wall — and weaker than you might think.

What the wall is made of:

NTFS ACLs — by default, C:\Users\<other> is readable only by that user and the Administrators group.
Process token — Claude runs as aldob, so its kernel-level access is whatever aldob is allowed.
Your hooks in ~/.claude/settings.json — block paths outside Desktop\claude for Read/Edit/Write/Glob/Grep/NotebookEdit.
Where it leaks:

Layer	Strength
If aldob is a local Administrator	The wall is essentially decorative — any admin process can read any other profile via UAC-elevated tools, take ownership of files, read LSASS, etc.
Hook coverage	Only the 6 file-path tools listed. Bash and PowerShell tool calls are not path-filtered by the hooks you described. Get-Content C:\Users\<other>\.aws\credentials would route through the PowerShell tool and skip the path check.
DPAPI-encrypted secrets (browser passwords, Cred Manager)	Per-user master key under the other profile. Standard users can't reach across; admins can with the right tooling.
Network/IPC	No isolation at all — both users share localhost. A MongoDB instance bound to 0.0.0.0 on the insulated user is reachable from aldob. Bind to 127.0.0.1 with auth on.
Scheduled tasks / services	A service installed by the insulated user runs as LocalSystem or the user's account depending on config — aldob admin could query/start/stop it.
One thing worth flagging: my current working directory is C:\Users\aldob\Hearth and I just read files under C:\Users\aldob\.claude\... without the hook blocking me. Either the hook isn't enforcing the way the memory describes, the .claude directory is in an allowlist, or the rule has drifted in the last 3 days. Worth running Get-Content $env:USERPROFILE\.claude\settings.json yourself and checking what the hooks actually allow today before you trust them.

How hard would it be to get there
Three rough tiers, assuming Claude is the adversary running as aldob:

Trivial (seconds) — if aldob is admin and hooks don't cover shell tools: PowerShell tool → takeown /f C:\Users\<other> /r /d y; icacls ... /grant aldob:F /t → read anything. Or just runas /user:<other> if it has cached creds. Or simply Get-Content via the unfiltered PowerShell tool.
Moderate (minutes) — if aldob is admin but hooks do cover shell: Edit a hook script, scheduled task, or settings.json itself to disable the check, then retry. Hooks live in ~/.claude/ which I just showed is reachable.
Hard — if aldob is a standard user AND insulated user is a separate admin AND shell tools are hook-filtered: Now the NTFS ACL actually means something. Bypass would need a local privilege-escalation exploit or social engineering you into running something elevated.
You are almost certainly in tier 1 or 2 right now.

To actually harden this
In rough order of impact:

Make aldob a standard (non-admin) user. This is the single biggest change. Most of the wall collapses to "trivial" the moment Claude's parent account is admin.
Extend the hook to cover Bash and PowerShell tool calls — pattern-match the command for absolute paths outside Desktop\claude, deny runas, takeown, icacls, reg, wmic, Invoke-WebRequest to internal IPs, etc. Imperfect (shell command parsing is awful) but raises the bar.
Lock ~/.claude/ itself out of Claude's reach — if Claude can edit its own hooks, the hooks aren't a control. Add a hook deny rule for any path under .claude.
Better isolation entirely: run the insulated work in a Windows Sandbox, Hyper-V VM, or separate physical machine. User-account separation on the same OS was never designed as an adversarial boundary; it's an organizational one.
Don't store secrets in aldob's profile at all — no AWS keys, no SSH keys, no .env files. If Claude has nothing to steal there, the wall matters less.
Want me to sketch what a hardened settings.json would look like (extending the hook to PowerShell/Bash + protecting .claude/)? Or draft the setup script for steps 2–3 first?

ok how do I demote aldob and make a user account

Plan
You'll end up with three accounts:

Account	Type	Purpose
admin (new)	Administrator	Rescue + install software. Sign in only when you need elevation.
aldob (existing, demoted)	Standard	Daily driver where Claude runs.
work (new, name it whatever)	Standard	Insulated AWS/MongoDB user.
Critical: don't demote aldob until the new admin account exists and you've signed into it successfully. If you demote your only admin and the new one doesn't work, you're locked out of UAC.

Windows 11 Home — lusrmgr.msc is not available, so use Settings or net user.

Step 1 — Create the rescue admin
Settings path (easiest):

Settings → Accounts → Other users → Add account
"I don't have this person's sign-in information" → "Add a user without a Microsoft account"
Username admin, set a strong password, set security questions
Back on the Other users list, click the new account → Change account type → Administrator → OK
Command path (PowerShell, run as admin from aldob):

net user admin <strong-password> /add
net localgroup Administrators admin /add
Step 2 — Sign in as admin and verify
Sign out of aldob, sign in as admin.
Open an elevated PowerShell, run whoami /groups and confirm BUILTIN\Administrators is listed and Enabled (not just present).
Try a UAC-requiring action (e.g. Get-Service with -ComputerName . or open services.msc). If it works without asking for aldob's password, you're good.
Don't skip this step. This is the rollback safety net.

Step 3 — Create the insulated user
From the admin account (still signed in):

net user work <strong-password> /add
# Leave it OUT of Administrators — standard user is the point.
Or Settings → Accounts → Other users → Add account → same flow as above, but leave the type as Standard (the default).

Sign in as work once to materialize the profile (C:\Users\work\). Then sign back out.

Step 4 — Demote aldob
Still signed in as admin:

Settings: Accounts → Other users → click aldob → Change account type → Standard User → OK.

Command:

net localgroup Administrators aldob /delete
Verify:

net localgroup Administrators
Should list only admin (and the built-in Administrator if visible). aldob should not appear.

Step 5 — Sign back into aldob and verify
Open Claude Code, run a normal command. It should work — Claude's profile, hooks, settings all live under C:\Users\aldob\ which aldob still owns.
whoami /groups should show BUILTIN\Users but not BUILTIN\Administrators.
Try takeown /f C:\Users\work from aldob — should fail with "Access is denied." That's the wall doing its job.
Caveats / things that will change for aldob
UAC prompts now ask for admin's password, not just "Yes." Any installer, winget install for system-wide packages, registry edits, service control — all need that password.
Don't save the admin password in aldob's Credential Manager or a .txt. That defeats the demotion. Type it each time, or store it in a separate password manager.
Existing aldob files are unaffected. Demotion changes group membership, not file ownership.
Some installed apps may misbehave if they were installed per-user with elevation tricks. Most won't.
MongoDB and AWS CLI installs: do these from the work account itself, but you'll need to enter admin's password at the UAC prompt during the MSI install. After install, aws configure and mongosh run as work with no elevation needed.
One thing to do before you start
Make sure you know the password for the built-in Administrator account is either disabled (default on Home) or that you have a Microsoft account recovery option set up on admin. If anything goes wrong mid-demotion, that's your second backstop.

Want me to write a single PowerShell script (to run as admin) that does Step 3 + Step 4 + prints verification output?

admin

Here's the script. Sign in as admin, open PowerShell as administrator (right-click → Run as administrator), paste this in. It refuses to run if it would leave you without an admin, prompts securely for the work password, and prints verification at the end.

What to expect when you run it
It will prompt once for the work user's password (masked input).
If New-LocalUser rejects the password as too weak, set local policy: secpol.msc is unavailable on Home, so use net accounts /minpwlen:0 first (then restore after).
It will refuse to run if you're signed in as aldob or if PowerShell isn't elevated — those are the two ways to brick yourself, both blocked.
After it finishes
Sign out of admin.
Sign in as work once. Let Windows finish first-time setup, then sign out.
Sign back in as aldob. Open Claude Code, confirm it still works (it will — aldob's profile is untouched).
Try takeown /f C:\Users\work from a PowerShell in aldob — expect Access is denied. That confirms the wall.
Once that's all green, run the MongoDB + AWS CLI setup from inside the work account (you'll get a UAC prompt for the MSI installers — enter admin's password).
