In earlier beta testing days of Windows 7, it was possible to remove the "Blur" effect from window borders (window titlebar, etc) but the functionality was removed in later builds. Even the RTM build doesn't contain this functionality.
We just needed to alter a DWORD value in Registry Editor and the Blur could be removed.
No need to get sad. "PacMani" @ DA has created a small batch script which replaces 2 RTM system files with the beta ones and also incorporates the required registry DWORD values automatically. So you can get the good old Beta functionality back in RTM build.

After:

Simply download the ZIP file using following link:
How To Instructions:
1. Extract downloaded ZIP file and run "Patch Blur x86.bat" file. If you are using x64 bit version, run "Patch Blur x64.bat" file.
2. It'll take a few seconds and you'll see window without blur.
3. If you want to put the blur back, run "Enable Blur.bat" file. And if again you decide to remove the blur, run "Disable Blur.bat" file.
4. Although you would not need to run "Unpatch Blur.bat" ever, but in case you want to restore the default system files back, run it.

It doesn't work for me on x86. It appears as if it was W7 Basic.

Simply edit stream file in aero.msstyle....
VG
^^ No. Its not about the Aero strip, its about the blur. You can't disable blur by editing the msstyles file.
@Frt45
Its working absolutely fine here. Did you try a restart?

Got an easier way. Look for the following Registry entry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM\ColorizationGlassReflectionIntensity
If absent create it as a DWORD. Set it to zero for no blur at all. Usually it is set at 50 by default.
After you do this change your theme to Basic. You will now see the blur gone. You can then choose any theme you want including Aero.
If you ever notice the blur is back just change the Reg entry to zero again, change to Basic, then to any theme you want.
This doesn't require files from the pre-RTM versions to work.

I restarted, logged off, and no luck. Do you know my problem, VG?
Nikolaj
Nice.
VG
Did you guys try to run the batch script as Administrator?
@Mike
Its defined by the msstyles file. You'll need to edit Stream image to modify the shadow.
