This is not enough for a bug report, I have no idea of what you're
trying to say.

When using Windows 8, I get this problem as well. It seems that the session 
files gets written to c:\Windows - but phpdesktop doesn't have the right 
permissions. This is the error I get when running phpLiteAdmin:

Warning: session_start(): open(C:\Windows\sess_*******, O_RDWR) failed: 
Permission denied (13) ...

What is the tmp directory showed in phpinfo()?

Have you tried setting the session save path?

    ini_set('session.save_path', 'C:/Windows/temp');

Try "C:/Windows/temp" or some other directory that your application 
has permission to write to.

Anyone having problems with writing session files will probably also
have problem uploading files, if so try setting the "upload_tmp_dir" 
option using ini_set() similarly to the "session.save_path" option.

Since PHP 5.5.0 there is an another php.ini option besides the
"session.save_path" and "upload_tmp_dir" that might interest us,
it's named "sys_temp_dir", but this one can be set only through
php.ini, it cannot be changed with ini_set().

In phpinfo() the save_path is set to "no value".

Can we set values in php.ini itself? Because doing ini_set for several 
third-party scripts would be a pain.

Adding this to php.ini seems to help indeed:

session.save_path = C:/Windows/temp

Yes, these are php.ini options, you can set them by editing the php.ini
file or set it dynamically via ini_set(), the advantage of the second
method is that you can check if the "C:/Windows/temp" really exists, as
user may be running Windows from another partition for exmaple D:/ and
hardcoding the path might fail in this case. There is an 
"auto_prepend_file" directive that you could use with third-party 
scripts to set the temp directory dynamically using ini_set():

TODO: Create an example in the www/ directory for using sessions and
uploading files, it should handle cases when the TMP/TEMP environment
variable is not set in Windows, thus the "session.save_path" or the
"upload_tmp_dir" options are empty in phpinfo().

A php example script will be added to the php desktop binaries with an
exaplanation that PHP temp environment variables should be set on this OS.

I have investigated the issue again and the problem was that the TMP 
environment variable was not set by the Mongoose webserver. Fixed in revision 
89f4820f0bf1. Added the upload and session examples.
