Here’s a clear, practical guide to fix the Windows 10 error:
**“We can’t sign in to your account”**
and the issue where Windows keeps logging you into a **temporary profile** every time.
This problem usually happens because Windows can’t load your user profile correctly.
---
## First, confirm the symptom
When you log in:
- You see a notification saying **we can’t sign in to your account**.
- Files/settings are missing.
- A **Temporary Profile** is loaded.
If all this is correct, here are the fixes.
---
# Fix 1 — Restart the PC (yes, really)
Temporary-profile issues sometimes resolve after one **full restart** (not shutdown + fast startup).
Do this:
1. Press **Shift** and click **Restart** from the Start menu.
2. Boot normally.
If the error remains, continue.
---
# Fix 2 — Log out and log back in to the same account
A temporary profile is often triggered by a locked profile file.
1. Press **Ctrl+Alt+Delete**
2. Choose **Sign out**
3. Log back in
If it still signs in as temp → go to next fix.
---
# Fix 3 — Check if your profile is corrupted (Registry fix)
⚠️ Only do this if you're comfortable editing the registry.
1. Press **Win + R**
2. Type **regedit** → Enter
3. Navigate to:
```
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
```
4. Look for two keys with the same long number **SID**, one with **.bak** at the end.
Typical scenario:
- `S-1-5-21-xxxxxxxx…`
- `S-1-5-21-xxxxxxxx….bak`
If found:
**A. Rename the non‑.bak key to .temp**
**B. Remove .bak from the other key**
**C. In the corrected key, set:**
- `State` = 0
- `RefCount` = 0
5. Reboot Windows.
This fixes most cases.

# Fix 4 — Check disk for errors
A damaged user profile can be caused by disk corruption.
Run:
1. Open Command Prompt as Administrator
2. Type:
```
chkdsk C: /f /r
```
3. Press Y when asked to restart.
Let it complete fully.
---
# Fix 5 — Create a new account and move your files
If the profile is too damaged, the easiest fix is:
1. Settings → Accounts → Family & other users
2. Add someone else to this PC
3. Create a local account or Microsoft account
4. Log into the new account
5. Move files from:
```
C:\Users\OldAccount\
```
This will permanently stop the temporary profile problem.
---
# Fix 6 — Windows Update bug (common)
Some Windows updates break profiles.
Try:
1. Settings → Update & Security → Windows Update
2. View update history
3. Uninstall the last update
---
# Fix 7 — Antivirus interference
Third‑party antivirus (Kaspersky, Bitdefender, Avast) can lock profile files and cause temp profiles.
Try disabling or uninstalling temporarily.
---
# Fix 8 — Check for low disk space
Less than 1GB on C: drive can break profile loading.
Make sure you have free space.
---
# Want step‑by‑step assistance?
If you tell me:
- Whether you can log in normally at any time
- If your profile folder still exists in `C:\Users`
- If this started after an update or restart
…I can give you exact steps tailored to your situation.
Just let me know what you see.
