Get Windows XP's Help Center on newer versions of Windows

Note 1: It isn't really functional, it's more for show than anything else

Note 2: I didn't test this too much, so it may cause issues, but it shouldn't, since it replaces only 1 system file

This has been tested on Windows 7, Windows 8.1 and Windows 10 LTSC 2016

Here are the steps:

1. Get the PCHEALTH.INF file from Windows XP. To do this, mount your Windows XP ISO (or put in an actual CD), go to the i386 folder, and get the PCHEALTH.IN_ file and use 7-Zip to extract PCHEALTH.INF

2. Open an Explorer window with TrustedInstaller rights. To do this, use a tool such as NSudo

3. Navigate to your extracted PCHEALTH.INF file, right click, and select Install. When prompted for files, point to the drive with the Windows XP CD. When prompted to replace a system file, click Yes, and reboot your computer when asked.

4. Open a command prompt as administrator, make sure you're in C:\Windows\System32 and run these commands:

%windir%\PCHealth\HelpCtr\Binaries\HelpSvc.exe /install2 /svchost netsvcs /regserver /RAInstall
%windir%\PCHealth\HelpCtr\Binaries\HelpHost.exe /regserver
%windir%\PCHealth\HelpCtr\Binaries\HelpCtr.exe /regserver
regsvr32 %windir%\PCHealth\HelpCtr\Binaries\brpinfo.dll
regsvr32 %windir%\PCHealth\HelpCtr\Binaries\msinfo.dll

After that, to launch Help Center, run:

%windir%\PCHealth\HelpCtr\Binaries\HelpCtr.exe -FromStartHelp

Here are screenshots of it on Windows 7 and 10 1607:
