Just wondering, if the Win version that you are trying is from Greenpois0n? 

I already jailbroken iphone 4s but failed to jailbreak my ipad 2. Haih....l

First time use CMD?

Let´s go.

First, ensure the compatible Firmwares:
iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
iPad2: 5.0.1 (9A405) <--- ONLY WIFI, NOT 3G

Download, version 0.4.3, Read post 3.

Unzip files into root dir, like C:

1. Press, in your keyboard WINDOWS+R (Run windows) and type: "CMD" (Without quotes), and press ENTER
2. On windows is open (BLACK WINDOWS) type the commands withouts quotes: "CD .."
3. "cd cinject_0.4.3"
4. Now your machine will stay that way: (C:\cinject_0.4.3>) <-- DO NOT TYPE THIS
5. Run first command withou quotes: (Submit by CAPSLOCKON)
a. "cinject.exe -i payloads/jailbreak.mobileconfig"
- IMPORTANT. On device, accept the script, and next next finish (without password)
6. "cinject.exe -j payloads"
- IMPORTANT. Wait the backup. Sugest try with blank A5 device.
7. "cinject.exe -w"
8. Try to start Absithe, if you get error database, go to setting and turn on VPN and try again

Good luck
