This guide is NOT affiliated, endorsed, or supported by Microsoft.

Word of Caution:

Please do not use kernelxp.dll wrapper as an excuse to continue using Windows XP RTM or SP1 as your primary Windows XP version.

Bugs:

Internet Explorer 7

If Internet Explorer 7 is installed on Windows XP RTM, and using the imm32.dll from another version, it will break the system, so you need to use just the XP RTM imm32.dll.

Therefore, as mentioned in the bugs section of legacy-windows-chrome-compat - You will not get Chrome 24 through 49, due to IMM32.DLL bug.
