Problem
While trying to open the certificate store using the MMC, I got a frequent error "Microsoft Management Console has stopped working"
In the event log I found an error
Faulting application name: mmc.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc808
Faulting module name: ntdll.dll, version: 6.1.7600.16385, time stamp: 0x4a5be02b

Faulting application start time: 0x01cafc1aa296b702

Faulting module path: C:\windows\SYSTEM32\ntdll.dll
Report Id: e5d7c685-680d-11df-85f7-90e6ba9ec58c
Workaround
The workaround is by opening the certificate store directly without using MMC
1.Click start
2.In run command type"certmgr.msc"
3.Click enter
