Where to check windows 7 status (RTM or not) :

Where to get it?

Underground source. Microsoft doesn’t release this version to public for free unlike beta version and RC. X86 (32bit version) and x64 (64 bit version) could be find there. Be sure to check SHA-1 key to ensure that your downloaded ISO is unmolded or untouched version.

What the…. How to check that. How on earth could I check my downloaded ISO SHA-1?

Use this open source SHA-1 (and also MD5) checker from sourceforge. Download here.

You may need to download java runtime to use that tool. Download java runtime here.

Run Ash’s MD5/SHA-1 Checker, click on open button.

It may take 2 to three minutes to check the SHA-1. Don’t worry if you don’t see any progress bar what so ever. As for myself, the screen above remain like that for 3 minutes or so. Just give it some time to abuse your CPU computing power okay (^_^).

Finally…after 3 minutes…

Ping pong…. I found out that my RTM Win7 SHA-1 doesn’t match original HAS-1 key. Why the hack this happen. Short answer, this ISO might not be the untouch version (if I am lucky, the uploader doesn’t put anything nasty but if I am not lucky, only heaven know what he put in this ISO).

Untouched SHA-1 key :     0xBC10F09B86DCBAF35B31B0E6FBA7D006ACAAD28D (where to check this key for entire list? Refer below)

My previous download :     606ce48c4f1af04fee97a6852aa382fb7899829e

Same name, same size but unfortunately not the very same file. Action: Delete L

Additional Info: As for now, I am not pretty sure to believe 5395DC4B38F7BDB1E005FF414DEEDFDB16DBF610 as untouch key or not (base on this website :

According to technet blog, actual untouch SHA-1 key as below :

Note : Even so, my previous downloaded ISO is not match with above SHA-1 key either. So, confirm delete and re-download. I personally believe technet blog more than anything else.

OMG, is there any easier way to check either the ISO is valid or not?

Yes it is actually. You may use Windows 7 ISO verifier to verify either your downloaded ISO is valid or not. No need for you to compare hash or SDA-1. It will do automatically with its known valid hash key (its databsase). The above method can be used at any files or iso (not limted to windows 7 only).

Can I use Win7 RC or Beta key in this RTM version?

No, you can’t. Without a proper key (or, ahem crack (hint : one of them is orbit30, so google it ^_^), Microsoft only allow you to use Win7 for 30 days + 3x rearm (total days, 120 days, not to shabby isn’t it). Orbit30 is not the only crack (what it did right now, is replacing Win7 RTM activation files with Win7 RC activation files). So, your RTM Win7 will expire March 2010. Need to wait better and proper crack. Cough cough. Academic purpose only right…right? XD

How to rearm Windows 7?

  1. Install Windows 7 without any product activation key.
  2. After installation is completed, use the Windows 7 for 30 days and wait for the remaining days left to activate Windows counting down to 0, or almost zero.
  3. When the activation grace period (or evaluation trial period) is almost expired or ended, log on to Windows 7 desktop, and open a Command Prompt window (i.e. type Cmd in Start Search and hit Enter).
  4. Type any of the following commands into the command prompt, and then hit Enter:

    sysprep /generalize

    slmgr.vbs –rearm

    rundll32 slc.dll,SLReArmWindows

    slmgr /rearm

  5. Reboot Windows 7 to enjoy another 30 days of free usage without worrying about activation nor even need to crack Windows 7.
  6. When the activation grace period countdown timer almost running down to 0 again, repeat the ‘rearm’ trick to enjoy another 30 days of Windows 7 for free. User can run the rearm command for maximum of 3 times.

Can I install windows 7 without DVD disc (by using pendrive or thumb drive)?

Yes you can. Further read : HERE

Why should I install win7 by using my pendrive or external hdd?

SPEED!!! If you have decent speed pendrive (for example even the cheapo Toshiba (sequential read 24 MBps), it is hell lot faster than installing from DVD disc. Furthermore, you help to save our earth (and your pocket) by not wasting optical disc (made by plastic, and plastic is petroleum product). Save the earth, yeah…you hear me right LoL. But, honestly, save the earth. Seriously. Furthermore, the step is totally newbie friendly.

How to check my current (installed) Windows 7 build?

From start menu à type winver

You will get something like this. (There is no expiry date because I decide to re-arm it instead of use RC activation crack. 120 days should be enough until October 2010. Honestly, genuine Windows 7 worth every single cent even at Malaysia :: Personal Opinion).

Err…what is RTM actually?

Accronym for Release to Manufacturer. Oppose to Beta or RC (Release Candidate), RTM is a complete software (or operating software in this case). Beta and RC well, it is beta right. Mean, still in testing. RTM is a complete copy, which Microsoft distribute this copy to PC or laptop manufacturer (even hardware vendor if I am not mistaken) such as Acer, Dell, HP etc. RTM version doesn’t has watermark or send report link anymore. In short, RTM code = retail code that you could buy at your local store this October.

What else eh….. feel free to dump your question or idea, critics etc in the comment box below.

Remove watermark (desktop) :

Use this tools instead : Download Here

You may need to turn OFF UAC –> restart –> Open this tool with administrative right –> restart –> enable your UAC back.


Remove Send Feedback : 

Run Registry Editor (RegEdit), and navigate to the following registry key:

HKEY_CURRENT_USER –> Control Panel –> Desktop –> FeedbackToolEnabled –> Set Value data as 0 (zero)


Note : If FeedbackToolEnabled registry not exist, you can add manually 

Add in a new DWORD (32-bit) Value named FeedbackToolEnabled, and then set its value data as 0. Restart your computer.
