If you want to remove password expiration do the following:

1. Click on Start button.
2. Type wmic
3. Right click listed program wmic and “Run as Administrator”
4. Now you can list accounts that have password expiration set:
   path Win32_UserAccount where PasswordExpires=TRUE get Name
5. And you can disable it – you will be prompted to confirm the change:
   path Win32_UserAccount where PasswordExpires=TRUE set PasswordExpires=FALSE

This is not really a missing answer, however, there are plenty of solutions which do not work well, or contain typos – mostly because of different quotes used in the command. This script allows changing the expiration at once for all users that have it set – and it does not contain any quotes

Anyway, this is so far the biggest failure I have encountered when using Windows 7 Home Premium edition: Force password expiration in home environment and do not provide a GUI how to disable it.

Error during signature verification.
Error encountered while validating:
Internal cryptographic library error.
Error Code: 0×2711

– Czech equivalent —
Chyba v průběhu ověřování podpisu.
Při ověřování se vyskytla chyba:

There is no info available on the internet what does it mean, so I contacted support and the answer was easy – I was signing the document with backup of my private key – there was no certificate present in that file, so there was not way how to calculate hash of the document. The solution is to export the private key including your certificate.

if [ -n "${SUDO_USER}" -a -d "/home/${SUDO_USER}/.vim" ]; then
alias vim="/usr/bin/vim --cmd \"set runtimepath+=/home/${SUDO_USER}/.vim\" -u /home/${SUDO_USER}/.vimrc"
fi


It took me quite a lot of googling to find the right combintation of $VIMRC, $VIMRUNTIME, $VIMINIT, $VIMHOME – and finally as you can see, none of those variables is used. Very usefull during debugging was to run vim with -V. to see where it looks for its configuration. And yes, I have tried putting the code to set the runtimepath to the .vimrc, but it would have to be conditional and this seems more clean.

# Or use just when needed
LC_TIME="POSIX" sar

sar is a command from systat package. It provides output in AM/PM format by default. Setting the locale LC_TIME to POSIX changes the time format to 24.

Missing drivers

When enabling the features, the installation requested usbhub.sys and usbd.sys. The first file was recommended by MS to be taken from the Windows XP SP3. I have downloaded the SP3 and extracted the file using 7zip:

7za x WindowsXP-KB936929-SP3-x86-ENU.exe i386\usb*.*

But the installation requested another file – usbd.sys, which is not part of the XP SP3 – so I have copied the file from my Windows 7 (C:\Windows\System32\drivers\usbd.sys).

Password prompt

With enabled integration features the VPC asks for password. As it turned out, it tries to do remote desktop connection to itself. It suggests Admin user but Password1 does not work – apparently the Admin account is missing completely. IE User does not work either, because this user does not have password and cannot make remote desktop connection to this PC. So the solution is to give IE User a password and to save the credentials during start up (you may need to delete credentials of the Admin user before using properties on the .VMC files.

This way I have solved all the problems I did not have when running the Compatibility images on Windows Vista with earlier images.

Zatím jediný způsob jak se toho nadobro zbavit pro mě byl zásah v registrech – smazal jsem rozložení z registrů:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\00020409]
“Layout Text”=”United States-International”
“Layout Display Name”=”@%SystemRoot%\\system32\\input.dll,-5026″
“Layout File”=”KBDUSX.DLL”
“Layout Id”=”0001″

<VirtualHost *:80>
 ServerName beta.example.com
 DocumentRoot /var/www/example

 <Location />
 AuthType basic
 AuthName "Top Secret Beta!"
 AuthUserFile /etc/httpd/htpasswd.beta
 Require valid-user
 </Location>

 <Location /upload-callback>
 Allow from all
 Satisfy Any
 </Location>

 <Directory /var/www/example>
 RewriteEngine On
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule !\.(swf|pdf|php|js|ico|txt|gif|jpg|png|css|rar|zip|tar\.gz)$ /index.php [L]
 </Directory>
</VirtualHost>

With this setup, the subdirectory will require valid user – because mod_rewrite is applied before <Location> and changes the URL, which no longer matches. You can change this by adding an alias:

Alias /upload-callback /var/www/example/index.php

Now all URLs will go through your nice url generator index.php, but the specified URL will be checked against <Location> and give access based on the Allow directive (in this case to everyone).

And indeed, these helpers caused the problem:

// UPGRADE: The following css helpers should now be used as:
// .css("top") or .css("top","30px")
jQuery.each("top,left,position,float,overflow,color,background".split(","), function(i,n){
  jQuery.fn[ n ] = function(h) {
    return h == undefined ?
      ( this.length ? jQuery.css( this[0], n ) : null ) :
      this.css( n, h );
  };
});

We have replaced position with xposition and our jQuery works as expected even with version 1.2.6.

For the command line ans svn+ssh access I created following files (based on some advice, which I found 4 years ago and did not notice a link):

/usr/local/bin/svn

#!/bin/sh
umask 002
/usr/bin/svn.orig "$@"

/usr/local/bin/svnserver

#!/bin/sh
umask 002
/usr/bin/svnserve.orig "$@"

As big surprise you will find that the web interface modifies files in the subversion repository - it removes write permission on group. I have solved this by adding following line to viewvc.cgi:
