# Interesting Windows Registry Keys
## **Windows system info**
### Version

### Timezone
* **`System\ControlSet001\Control\TimeZoneInformation`**: TimeZone
### Last Access Time
* **`System\ControlSet001\Control \Filesystem`**: Last time access \(by default it's disabled with `NtfsDisableLastAccessUpdate=1`, if `0`, then, it's enabled\).
* To enable it: `fsutil behavior set disablelastaccess 0`
### Shutdown Time
* `System\ControlSet001\Control\Windows`: Shutdown time
* `System\ControlSet001\Control\Watchdog\Display`: Shutdown count \(only XP\)
### Network Information
* **`System\ControlSet001\Services\Tcpip\Parameters\Interfaces{GUID_INTERFACE}`**: Network interfaces
* **`Software\Microsoft\Windows NT\CurrentVersion\NetworkList\Signatures\Unmanaged` & `Software\Microsoft\Windows NT\CurrentVersion\NetworkList\Signatures\Managed` & `Software\Microsoft\Windows NT\CurrentVersion\NetworkList\Nla\Cache`**: First and last time a network connection was performed and connections through VPN
* **`Software\Microsoft\WZCSVC\Parameters\Interfaces{GUID}` \(for XP\) & `Software\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles`**: Network type \(0x47-wireless, 0x06-cable, 0x17-3G\) an category \(0-Public, 1-Private/Home, 2-Domain/Work\) and last connections
### Shared Folders
* **`System\ControlSet001\Services\lanmanserver\Shares\`**: Share folders and their configurations. If **Client Side Caching** \(CSCFLAGS\) is enabled, then, a copy of the shared files will be saved in the clients in `C:\Windows\CSC` \(there are different options\)
### AutoStart programs
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Run`
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\RunOnce`
* `Software\Microsoft\Windows\CurrentVersion\Runonce`
* `Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run`
* `Software\Microsoft\Windows\CurrentVersion\Run`
### Explorer Searches
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\WordwheelQuery`: What the user searched for using explorer/helper. The item with `MRU=0` is the last one.
### Typed Paths
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths`: Paths types in the explorer \(only W10\)
### Recent Docs
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs`: Recent documents opened by the user
* `NTUSER.DAT\Software\Microsoft\Office{Version}{Excel|Word}\FileMRU`:Recent office docs. Versions:
* 14.0 Office 2010
* 12.0 Office 2007
* 11.0 Office 2003
* 10.0 Office X
* `NTUSER.DAT\Software\Microsoft\Office{Version}{Excel|Word} UserMRU\LiveID_###\FileMRU`: Recent office docs. Versions:
* 15.0 office 2013
* 16.0 Office 2016
### MRUs
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\LastVisitedMRU`
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\LasVisitedPidlMRU`
Indicates the path from where the executable was executed
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\Op enSaveMRU` \(XP\)
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\Op enSavePidlMRU`
Indicates files opened inside an opened Window
### Last Run Commands
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU`
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\Policies\RunMR`
### User AssistKey
* `NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\UserAssist\{GUID}\Count`
The GUID is the id of the application. Data saved:
* Last Run Time
* Run Count
* GUI application name \(this contains the abs path and more information\)
* Focus time and Focus name
## Shellbags
When you open a directory Windows saves data about how to visualize the directory in the registry. These entries are known as Shellbags.
Explorer Access:
* `USRCLASS.DAT\Local Settings\Software\Microsoft\Windows\Shell\Bags`
* `USRCLASS.DAT\Local Settings\Software\Microsoft\Windows\Shell\BagMRU`
Desktop Access:
* `NTUSER.DAT\Software\Microsoft\Windows\Shell\BagMRU`
* `NTUSER.DAT\Software\Microsoft\Windows\Shell\Bags`
To analyze the Shellbags you can use [**Shellbag Explorer**](https://ericzimmerman.github.io/#!index.md) ****and you will be able to find the **MAC time of the folder** and also the **creation date and modified date of the shellbag** which are related with the **first time the folder was accessed and the last time**.

Note 2 things from the following image:
2021-05-13 22:59:50 +00:00
1. We know the **name of the folders of the USB** that was inserted in **E:**
2. We know when the **shellbag was created and modified** and when the folder was created an accessed

## USB information
### Device Info
The registry `HKLM\SYSTEM\ControlSet001\Enum\USBSTOR` monitors each USB device that has been connected to the PC.
Within this registry it's possible to find:
* The manufacturer's name
* The product name and version
* The Device Class ID
* The volume name \(in the following images the volume name is the highlighted subkey\)
![](../../../.gitbook/assets/image%20%28489%29.png)
![](../../../.gitbook/assets/image%20%28481%29.png)
Moreover, checking the registry `HKLM\SYSTEM\ControlSet001\Enum\USB` and comparing the values of the sub-keys it's possible to find the VID value
![](../../../.gitbook/assets/image%20%28476%29.png)
With the previous information the registry `SOFTWARE\Microsoft\Windows Portable Devices\Devices` can be used to obtain the **`{GUID}`**:
![](../../../.gitbook/assets/image%20%28486%29.png)
### User that used the device
Having the **{GUID}** of the device it's now possible to **check all the NTUDER.DAT hives of all the users** searching for the GUID until you find it in one of them \(`NTUSER.DAT\Software\Microsoft\Windows\CurrentVersion\Explorer\Mountpoints2`\)
![](../../../.gitbook/assets/image%20%28485%29.png)
### Last mounted
Checking the registry `System\MoutedDevices` it's possible to find out **which device was the last one mounted**. In the following image check how the last device mounted in `E:` is the Thoshiba one \(using the tool Registry Explorer\).
![](../../../.gitbook/assets/image%20%28483%29.png)
### Volume Serial Number
In `Software\Microsoft\Windows NT\CurrentVersion\EMDMgmt` you can find the volume serial number. **Knowing the volume name and the volume serial number you can correlate the information** from LNK files that uses that information.
Note that when a USB device is formatted:
* A new volume name is created
* A new volume serial number is created
* The physical serial number is kept
### Timestamps
In `System\ControlSet001\Enum\USBSTOR{VEN_PROD_VERSION}{USB serial}\Properties{83da6326-97a6-4088-9453-a1923f573b29}\` you can find the first and last time the device was connected:
* 0064 -- First connection
* 0066 -- Last connection
* 0067 -- Disconnection
