Windows X's Live recommends:
Before and after making any changes to your system or installing any software including Seven Transformation Pack, we strongly recommend you check Windows for registry errors.

After 7.0 release, I was told by a few users that patcher cause their system unstable. Some case specified this issue specially in explorer. The possible conclusion I came up with is non-English version of Windows 7 (or maybe Vista? I guess not since I didn't hear much about this in Seven Transformation Pack but who knows) isn't compatible with patched English version of theme engine files patched data is machine specific which will cause system unstable in some machine configurations. For whatever reason, I've switched patching engine to solely dedicated deepxw's universal theme patcher and release this as frontend though I really can't say this will fix it for sure due to some reports in Test Edition of Snow Transformation Pack that has very similar issue despite I use universal theme patcher.

Changes in version 7.1
-Changed patching engine to deepxw's universal theme patcher
-Fixed restore not available after patching in some system like Windows 7 x64
-Improved algorithm for program to be more safe in some unexpected cases
