Window$ Stuff

Things I thought I would never have to look at again but is somehow, quite consistently, forced to tinker with from time to time

Disclaimer: The stuffs I have here are only for my personal note (I got most of them from online resources - kudos to the original resource). If you want to try the same thing based on this, I cannot be held responsible if something goes wrong .

Get 'Open Command Prompt Here' Option in Windows Explorer

Windows 7: Hold 'Shift' key while right-clicking on a folder in Windows explorer

Turn On or Off Guest Account in Command Prompt

In Administrator's command prompt only…

To Turn On the Guest Account
```
net user Guest /active:yes
```
To Turn Off the Guest Account
```
net user Guest /active:no
```

Create Linux Boot Entry on Windows using BCDEdit

install Linux boot loader to partition boot block
- save image (e.g. if partition is /dev/sda3):
```
dd if=/dev/sda3 of=linux.bin bs=512 count=1
```
- copy this file to Windows partition (root of C: drive is best option)
boot into Windows (I tried this on 7)
- we will be modifying the boot configuration data
  - to backup:
```
bcdedit /export backup.bcd
```
  - to restore (later?):
```
bcdedit /import backup.bcd
```
- create an entry
```
bcdedit /create /d "Linux" /application bootsector
```
  - note the returned identifier (ID)
- point to partition where the image file is copied (e.g. if drive C)
```
bcdedit /set [ID] device partition=c:
```
- point to file with full path (e.g. if \linux.bin)
```
bcdedit /set [ID] path \linux.bin
```
- position entry at the end?
```
bcdedit /displayorder [ID] /addlast
```
- set 30s timeout, in case not set previously
```
bcdedit /timeout 30
```
to delete this entry (later?)
```
bcdedit /delete [ID]
```

More BCDEdit stuffs

On Windows 8.1 (and above?), the Windows Recovery Environment is disabled by default on UEFI systems (helps to boot faster). To get access, enable using BCDEdit:

bcdedit /set {default} bootmenupolicy legacy

To revert to original settings:

bcdedit /set {default} bootmenupolicy standard

Do note that we need to run command prompt as Administrator when doing this.

Remove Services

Check list of services, type
```
Win+R and run 'services.msc'
```
Open a command prompt as administrator
To remove, type (insert double quotes if the name has any whitespace character)
```
sc delete ServiceName
```
Refresh the list (F5) and it should be gone

System Event Error

I got this error:

Windows could not connect to the System Event Notification Service service...

open a command prompt as administrator
type
```
netsh winsock reset
```
- note: can also run this to try and fix failing to get ip address
restart

Using diskpart

Disk partitioning utility on Windows is diskpart (other than using GUI-based disk manager). It create MBR partition table.

e.g. To create single FAT32 partition in SD card, open command prompt as administrator and run diskpart.

list all disk
```
> list disk
```
- identify sd card id <n>
select sd card
```
> select disk <n>
```
list all available partitions
```
> list part
```
select partition id {n}
```
> select part {n}
```
remove selected partition
```
> delete part
```
repeat last two steps for each partition found
create single partition
```
> create part primary offset=1024
```
- note offset value is in kilobytes
exit and format as FAT32
