A problem has been detected and Windows has been shut down to prevent damage to your computer.
DRIVER_IRQL_NOT_LESS_OR_EQUAL
Restart your computer if this is the first time you have encountered this halt error screen. In the event that this screen recurs, proceed with the following procedures:
Ensure that any new hardware or software has been installed correctly. If this is a new installation, consult your hardware or software manufacturer for any necessary Windows updates.
If the issue persists, it is recommended that any recently installed hardware or software be disabled or removed. Disable BIOS memory options, including caching and shadowing. To remove or disable components in Safe Mode, restart your computer, press F8, select Advanced Startup Options, and then select Safe Mode.

The program can't start because MSVCP100.dll is missing from Lex Hasher's computer. Try reinstalling.
Post-Incident Analysis: Mission Restoration
Troubleshooting in an enterprise environment requires isolating causality from mere symptoms. This lab tests your ability to correlate user-mode errors with filesystem states under the pressure of high-visibility alerts.
1. Signal vs. Noise: The BSOD "Red Herring"
The DRIVER_IRQL_NOT_LESS_OR_EQUAL BSOD is a kernel-mode failure, but Lex Hasher reports a specific application fault. In Tier 2 support, you must learn: Don't anchor on the scariest screen.
2. Root Cause: Visual C++ Runtime Dependencies
The missing MSVCP100.dll library belongs to the Microsoft Visual C++ 2010 Redistributable. Applications compiled in C++ require these shared libraries to interface with the OS. If a single .dll is missing, the entire application runtime collapses during initialization.
3. Log Triage: Correlation Over Collection
Forensic triage involves matching the Application Error (Index 1983) with the timeline of Lex Hasher’s reported deployment failure.
- Distractor (Time-Service): A standard NTP sync warning. Benign.
- Distractor (DistributedCOM): Permission warnings that occur on almost every healthy Windows machine.
- Index 1983: The "Smoking Gun." Confirms Testing.exe is the crashed process.
4. Command Intent: Verifying Evidence
The CLI is used to confirm what the GUI claims. ls msvc* provides physical proof that while other runtime versions (110) exist, the required 100 module is absent from System32.
- tasklist | sort: Proves Testing.exe is attempting to start (PID assigned) but lacks the stability to persist.
- Get-WmiObject: Validated that Lex Hasher's hardware (LEX-HASHER-PC) had sufficient disk space (62GB+) to complete the remediation.
5. The Enterprise Angle: SCCM Incomplete Deployments
Why did this only affect Lex? SCCM deployments often rely on Detection Methods. If a package marks itself as "Successful" even if a prerequisite failed to install locally, you end up with "Incomplete Deployments." Restoration from a Gold Image (USER-PC01) ensures the library hash matches the company baseline.
