First off, all credits go to this guy. I’m just listing the steps on how I did it in Windows 7 with PHP 5.3. Also, I tested this using WampServer but I believe it should work on any PHP install.

Install memcached

Download the Memcached Win32 library here: http://code.jellycan.com/memcached. Just get the Win32 binary (direct link). Extract the downloaded archive file in a directory (e.g. c:\memcached). There should be amemcached.exe in there.
Run a command prompt as an administrator. Some info on how to do that here.
Install memcached as a service. Go to the memcached directory, type and run:
```
memcached -d install
```
If you get an error saying “MSVCP71.dll is missing”, see this page for a solution.
Start the memcached service by running:
```
memcached -d start
```
You can verify if memcached is running by executing this in the command line:
```
wmic process get description, executablepath | findstr memcached.exe
```
You should see a result list showing memcached.exe and its full path.

Install PHP Memcache extension (php_memcache.dll)

Chances are you don’t have php_memcache.dll in your PHP extensions yet. ~~You can download a build of it here.~~Basu has noted in the comments that VC6 builds are no longer available from that link. You can download the correct build here.
The archive should contain php_memcache.dll. Extract the archive to your php extensions directory. On my system (WampServer), this was C:\wamp\bin\php\php5.3.0\ext.
Edit php.ini, add this line to enable the extension:
```
extension=php_memcache.dll
```
Or if you’re using WampServer, restart it and enable the extension through the WampServer system tray menu.
