I'm looking to reinstall Apache 2.2.25 since I continue to get these errors in the Windows Application log every 2-5 minutes:

Faulting application name: httpd.exe, version: 2.2.25.0, time stamp: 0x51dd049c
Faulting module name: zlib1.dll, version: 1.2.3.0, time stamp: 0x4790446a
Exception code: 0xc0000005
Fault offset: 0x00002bad
Faulting process id: 0x38e8
Faulting application start time: 0x01cfbfd70cdfbc4f
Faulting application path: C:\Apache2\bin\httpd.exe
Faulting module path: C:\Apache2\bin\zlib1.dll
Report Id: 745f20de-2bca-11e4-bd5d-002590f28d7e

If the new install doesn't work or if there are some "issues", can I simply restore the Apache2 directory from backup and then I'll just be back where I started? I thought about just renaming the current install to something like c:\apache2_old and if something fails, I can delete the new install and rename c:\apace2_old back to c:\apache.

What do you all think?
