# Disabling TPM
## Method 1: BIOS (Recommended)
1. Restart PC and enter BIOS (F2, Del, F12)
2. Look under "Security," "Advanced," or "Trusted Computing"
3. Find "TPM Device" or "Security Device"
4. Set to "Disabled"
5. Save (F10) and restart
## Method 2: Disable Services
Run CMD as Administrator:
```
sc stop tpm
sc config tpm start= disabled
sc stop TPMConnect
sc config TPMConnect start= disabled
sc stop TBS
sc config TBS start= disabled
```
Restart PC.
## Method 3: Registry
1. Press `Windows + R` → type `regedit`
2. Navigate to:
```
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TPM
```
3. Change "Start" value to `4`
4. Repeat for:
* `Services\TBS`
* `Services\TPMConnect`
Restart PC.
## Method 4: Remove TPM.sys (Advanced)
Backup Required
This modifies system files. Create backup first.
Run CMD as Administrator:
```
# Backup
copy C:\Windows\System32\drivers\tpm.sys C:\tpm_backup.sys
# Take ownership
takeown /f C:\Windows\System32\drivers\tpm.sys
icacls C:\Windows\System32\drivers\tpm.sys /grant administrators:F
# Rename
ren C:\Windows\System32\drivers\tpm.sys tpm.sys.old
```
Restart PC.
## Verify TPM Status
**Check status:**
```
tpm.msc
```
or
```
Get-Tpm
```
## Restore TPM
**If renamed:**
```
ren C:\Windows\System32\drivers\tpm.sys.old tpm.sys
```
**If backed up:**
```
copy C:\tpm_backup.sys C:\Windows\System32\drivers\tpm.sys
```
**Re-enable services:**
```
sc config tpm start= auto
sc config TPMConnect start= auto
sc config TBS start= auto
```
Important
* Some Windows features require TPM
* Create system restore point first
* Keep backup of tpm.sys
* Windows Updates may re-enable TPM
## Troubleshooting
**Services Keep Re-enabling**
* Use both registry and service methods
* Check Windows Updates
* Use Group Policy method
**Boot Issues**
* Boot in safe mode
* Restore from backup
* Use system restore point

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://ghostware.gitbook.io/ghostware/getting-started/disabling-tpm.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
