I don't know how to update patches for magento. I tried cygwin in Windows but without success:
Can anybody help me to solve these problems?
To get patches for Magento CE:
To apply a Magento patch:
Enter the following command as a user with sufficient privileges to write to Magento files (typically, the web server user or root):
A message such as the following displays to confirm the patch installed successfully:
Patch was applied/reverted successfully.
Install a Linux inspired shell in windows
For example find git for windows online
Use the bundled shell that comes with it.
Git for Windows provides a BASH emulation used to run Git from the command line. *NIX users should feel right at home, as the BASH emulation behaves just like the "git" command in LINUX and UNIX environments.
Then you should be able to execute patch files as per docs
