To enable full context menu, run

reg add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve

and restart the explorer process.

To enable the default Windows 11 right-click context menu, run

reg delete "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}" /f

Clear System Tray Icons Cache

reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\IconStreams" /f
reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\PastIconsStream" /f

Backup/Restore/Delete Wireless Profiles via `netsh`

Backup to current folder: netsh wlan export profile folder=.\.
Restore from current folder to all users: for /r .\ %%f in (*.xml) do (netsh wlan add profile filename="%%f" user=all).
Delete all wireless profiles: netsh wlan delete profile name=*.

Backup/Restore VPN settings

Backup: Go to %appdata%\Microsoft\Network\Connections\ and backup the Pbk folder.
Restore: Restore the copied Pbk folder.

Backup and Restore Windows partitions with Clonezilla

I use GPT partition table.
I use a Arch Linux live USB with pre-installed Clonezilla to backup my Windows EFI boot partition and the main Bitlocker-encrypted partition containing the whole system. I also keep a copy of the following information:
- Recovery key of the Bitlocker-encrypted partition.
- The PARTUUIDs of both partitions, which can be obtained via blkid in Arch Linux.
- The disk layout (you can get by running fdisk -l in Arch Linux). This is necessary in case you have a new disk and want to restore Windows to that disk.
I saved Windows partitions as Clonezilla images. You may also backup the whole disk, not just the partitions.

After cloning with Clonezilla, verify that the PARTUUIDs of the partitions are matched. If this is not the case, follow this instruction to change their PARTUUIDs. I made a copy of an example for a disk with GPT partition table. Here, /dev/sda2 is the partition whose PARTUUID will be changed. Instead of using a random PARTUUID as in the example, enter the saved PARTUUID.

$ sudo gdisk /dev/sda
[sudo] password for mook: 
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): x                                       # enter x to change to experts menu

Expert command (? for help): c                                # enter c to change PARTUUID
Partition number (1-2): 2                                     # enter the number of the partition you want to change
Enter the partition's new unique GUID ('R' to randomize): r 
New GUID is 76349364-D66C-4C19-B422-237A0D2DB9F5

Expert command (? for help): m                                # enter m to go back to main menu

Command (? for help): w                                       # enter w to write the change to disk

Command (? for help): q                                       # enter q to exit gdisk
$

In some cases, the UEFI boot entry may change and fails to load the correct Windows partition. Follow this instruction to re-create a “Windows Boot Manager” with efibootmgr. I made a copy of an example here, where /dev/sdb2 is the Windows EFI partition.
```
sudo efibootmgr -c  -L "Windows Boot Manager" -l "\EFI\Microsoft\Boot\bootmgfw.efi" -d /dev/sdb -p 2
```

`C:\usr\snmp\persist\snmpapp.conf` keeps appearing

The folder C:\usr appears in my C:\ drive and even when I removed it, after rebooting Windows, it appears again. It contains a single directory persist and that directory has only one file named snmpapp.conf with the following content.

#
# net-snmp (or ucd-snmp) persistent data file.

From this page, I figure out that this is because I added a Kyocera printer to my list of printers in Windows.

Firefox show `MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING` error when entering a support.microsoft.com page

See this page for more details. To fix the issue, follow this workaround:

Open a tab and type about:config in the address bar.
Once in, type ocsp in the config search bar.
Toggle the parameter security.ssl.enable_ocsp_stapling from true to false.

Vim

See this page for the installations and configurations in Arch Linux.

Installation

Via Chocolatey
```
choco install -y vim python3
```
My $VIM directory (obtained by openning Vim and run :echo $VIM) is C:\tools\vim.
Copy C:\tools\vim\vim82\gvimrc_example.vim to C:\tools\vim\_gvimrc.
Nerd Fonts is nice and useful. I have to convert OTF fonts to TTF (e.g., see this python script) in oder to use these fonts with GVim. In particular, I use the MonacoB Nerd Font Mono font which I installed by downloading the OTF fonts from this repository and converting them to TTF fonts. My converted fonts are here .

Plugins

I use pathogen to manage Vim’s plugins. Simply download pathogem.vim and place it at the folder C:\tools\vim\vim82\autoload where Vim is installed. Add execute pathogen#infect() and filetype plugin indent on " Load plugins according to detected filetype to C:\tools\vim\_gvimrc. Create the folders %userprofile%\vimfiles\autoload and %userprofile%\vimfiles\bundle to store plugins managed by pathogen.
vim-colors-solarized can be installed by cloning its repository from GitHub and place at %userprofile%\vimfiles\bundle. Add
```
syntax enable
set background=dark
colorscheme solarized
```
to C:\tools\vim\_gvimrc.

vimtex can be installed similarly. My configuration for this plugin is as follows. Replace <your-username> with your username in Windows.

" settings for vimtex
let g:tex_flavor = 'latex'  
let g:vimtex_fold_enabled = 1
call deoplete#custom#var('omni', 'input_patterns', {
    \ 'tex': g:vimtex#re#deoplete
    \})
let g:vimtex_quickfix_mode = 0
" Disable custom warnings based on regexp
let g:vimtex_quickfix_ignore_filters = [
  \ 'Underfull \\hbox*',
  \ 'Overfull \\hbox*',
  \ 'Package hyperref Warning*'
  \]
" settings for sumatraPDF
let g:vimtex_view_general_viewer = 'C:\Users\<your-username>\AppData\Local\SumatraPDF\SumatraPDF.exe'
let g:vimtex_view_general_options
 	\ = '-reuse-instance -forward-search @tex @line @pdf'

Additionally, set the inverse search command line (from the SumatraPDF’s menu, choose Settings > Options...) in SumatraPDF as C:\tools\vim\vim82\gvim.exe --remote-silent +%l "%f". This page contains detailed settings for Texmaker and TeXstudio.

vim-airline and vim-airline-themes can be installed similarly. My configuration for these plugins are as follows.
```
" settings for airline
let g:airline_theme='solarized'
let g:airline_solarized_bg='dark'
```

Shougo/deoplete.nvim, roxma/nvim-yarp, and roxma/vim-hug-neovim-rpc can be installed similarly. Note that these plugins require some Python packages, so run pip install msgpack pynvim in a cmd. My configuration for these plugins are as follows.

" python
let g:python3_host_prog='C:/Python310/python.exe'
 
" deoplete settings
let g:deoplete#enable_at_startup = 1 " use deoplete for autocompleting
call deoplete#custom#var('omni', 'input_patterns', {
 	 \ 'tex': g:vimtex#re#deoplete
 	\})

SirVer/ultisnips and honza/vim-snippets can be installed similarly. Some other plugins are

Colors in Windows Command Line Prompt

See this guide for more details.

Depending on which colorscheme you like, clone lifepillar/vim-solarized8 or jacoborus/tender.vim to %userprofile%\vimfiles\bundle, as we did for other plugins.

Add the following to C:\tools\vim\_vimrc.

" If you have vim >=8.0 or Neovim >= 0.1.5
if (has("termguicolors"))
  set termguicolors

set background=dark

Using `vim-latex-suite` instead of `vimtex`

Clone vim-latex/vim-latex and place it at %userprofile%\vimfiles\bundle.
To avoid confliction, comment out settings for vimtex in C:\tools\vim\_gvimrc.
Add the installed folder of SumatraPDF (in my case is C:\Users\<my-user-name>\AppData\Local\SumatraPDF) to Windows’ Path environment variable. As before, set the inverse search command line for SumatraPDF (if it has not already been set) to use with GVim.

My settings for vim-latex-suite:

" settings for vim-latexsuite
"let b:suppress_latex_suite = 1 " suppress the loading of Latex-Suite
let g:Tex_DefaultTargetFormat = 'pdf'
let g:Tex_CompileRule_pdf = 'latexmk -pdf -interaction=nonstopmode -synctex=1 $*'

let g:Tex_ViewRule_pdf = 'SumatraPDF' " don't place a path here, otherwise forward-search may fail

VPN connection error `The parameter is incorrect`

From this page.

Run the following commands as Admin

netsh int ip reset
netsh int ipv6 reset
netsh winsock reset

Open Device Manager, Find Network Adapters, Uninstall WAN Miniport drivers (IKEv2, IP, IPv6, etc), Click Action > Scan for hardware changes. The adapters you just uninstalled should come back.

MSEdgeRedirect

From its homepage,

A Tool to Redirect News, Search, Widgets, Weather and More to Your Default Browser This tool filters and passes the command line arguments of Microsoft Edge processes into your default browser instead of hooking into the microsoft-edge: handler, this should provide resiliency against future changes. Additionally, an Image File Execution Options mode is available to operate similarly to the Old EdgeDeflector. Additional modes are planned for future versions. No Default App walkthrough or other steps, just set and forget.

I installed the tool via Chocolatey using choco install -y msedgeredirect.I also set startpage.com as my default search engine via the URL https://www.startpage.com/sp/search?query=. (Just put %s after = if you want to set up with Firefox in iOS.)

ZaDark - Dark Theme for Zalo

See this page or this page for more information. Basically, just download the latest ZIP archive, extract it, close Zalo (if it opens), and run the EXE file.
