It is totally reversible, just click on the patcher, it will take like 2 minutes, your theme will turn to classic, it will prompt reboot. Reboot and you can use custom themes from sites like DA. Then when you get tired, or when you want to install the next service pack just click on the patcher again, follow the prompts, reboot and your back to the unpatched uxtheme.dll.
OK. Once the patch is installed/applied can you still use the default XP theme or do you have to unpatch again to use it?
