❓ Complete FAQ

Is my 2017 PC compatible?
⚠️ Probably, but verification needed

2017 PCs are in a gray zone. It all depends on the exact processor:
  • Intel 7th generation (Kaby Lake: i7-7700K, i5-7600K) → ❌ Incompatible
  • Intel 8th generation (Coffee Lake: i5-8400, i7-8700K) → ✅ Compatible
The best way to know: download PC Health Check and run the verification in 30 seconds.
Can I bypass TPM and CPU requirements?
⚠️ Yes technically, but very risky

Methods exist (Rufus, registry modification), but consequences are real:
  • Blocked updates: Windows Update may refuse feature updates
  • ⚠️ Permanent warning message at bottom right of screen
  • No Microsoft support in case of issues
Our recommendation: If your PC is incompatible, stay on Windows 10 until October 2025, then consider hardware upgrade or a new PC.
How much does a hardware upgrade cost?
💰 Between $30 and $400 depending on blocking component

Here are the actual costs (2025 prices):

Budget solutions:
  • RAM (4 → 8 GB): $30-40
  • 256 GB SATA SSD (replaces HDD): $25-35
  • Total: ~$60-75 to unlock most compatible CPUs

Heavy solutions (incompatible CPU):
  • Intel i5-12400F processor: $150
  • B660 motherboard: $100-130
  • Total: ~$250-280 (requires Windows reinstallation)
Will Windows 10 still work after October 14, 2025?
⚠️ Yes, but without protection

Windows 10 will continue to work normally after October 2025, BUT:

What stops:
  • ❌ Security patches for newly discovered vulnerabilities
  • ❌ Feature updates
  • ❌ Official Microsoft support

The risk: Each day after October 2025, your PC becomes more vulnerable to cyberattacks. Hackers primarily target unpatched systems.
Does DirectStorage work on Windows 10?
⚠️ Partially (version 1.0 only)

DirectStorage exists in two versions:

DirectStorage 1.0 (Windows 10 + 11)
  • ✅ Direct GPU → SSD loading
  • ⚠️ CPU decompression (bottleneck)
  • ⚠️ Limited gains: -20 to -30% loading time

DirectStorage 1.1 (Windows 11 only)
  • ✅✅ Direct GPU → SSD loading
  • ✅✅ GPU decompression (GDeflate)
  • ✅✅ Massive gains: -60 to -75% loading time
  • ✅✅ Frees 40% of CPU in-game

For gamers: Windows 11 has become essential to fully enjoy AAA games in 2025.
Is my 2018 laptop compatible?
✅ Most likely yes!

2018 laptops generally have:
  • ✅ Intel 8th gen processor (i5-8250U, i7-8550U) → Compatible
  • ✅ TPM 2.0 (often disabled, activate in BIOS)
  • ✅ UEFI + Secure Boot

Action to take:
  1. Check with PC Health Check
  2. If "TPM not found" → Enter BIOS (F2 at startup) and enable Intel PTT
  3. Restart and re-run PC Health Check → Should pass ✅
Is 8 GB of RAM really enough?
✅ Yes for office work, ⚠️ borderline for modern gaming

Actual tests (Tom's Hardware, January 2025):

Office work (Chrome + Office + Teams):
  • 8 GB RAM: Smooth up to 15-20 Chrome tabs ✅
  • 16 GB RAM: Comfortable up to 40+ tabs ✅✅

1080p gaming:
  • 8 GB RAM: 2020-2022 games OK, 2024-2025 games borderline ⚠️
  • 16 GB RAM: All current games smooth ✅✅

Our recommendation:
  • 8 GB = OK if tight budget + office work only
  • 16 GB = 2025 sweet spot (guaranteed comfort 3-5 years)
  • 32 GB = 1440p/4K gamers and content creators
Do I really need an NVMe SSD or is SATA SSD enough?
✅ A SATA SSD is sufficient for 90% of uses

Actual gains comparison:

Usage HDD → SATA SSD SATA SSD → NVMe Gen3
Boot Windows 11 🚀 -70% (48s → 14s) 📈 -20% (14s → 11s)
Launch Photoshop 🚀 -80% (38s → 8s) 📈 -25% (8s → 6s)
Copy 10 GB files 🚀 -75% (85s → 22s) 📈 -18% (22s → 18s)

When to prefer NVMe Gen3/Gen4?
  • ✅✅ Gaming with DirectStorage (Forspoken, Ratchet & Clank)
  • ✅✅ 4K video editing (Premiere Pro, DaVinci Resolve)
  • ✅✅ Regular massive transfers (photographers, videographers)
  • ✅ Multiple virtual machines

Our verdict:
  • Already have SATA SSD? → Don't change, performance is excellent
  • Buying new in 2025? → Get NVMe Gen3 (same price as SATA)
  • Hardcore gamer? → NVMe Gen4 for optimal DirectStorage

📈 2025 Compatibility Statistics

Based on 5000+ forum verifications (Le Crabe Info, Tom's Hardware)

Incompatibility Reason % of PCs Rejected Solution Cost
TPM 2.0 disabled 41% ✅ BIOS activation (5 min) 💰 Free
Old processor 35% ❌ Upgrade required $200-400
Secure Boot disabled 28% ✅ BIOS activation (5 min) 💰 Free
Legacy mode (MBR) 22% ✅ GPT conversion (30 min) 💰 Free

✅ Optimistic conclusion: 64% of "incompatible" PCs are due to BIOS settings → Free and quick solution in 5-30 minutes!

✅ Conclusion: Act Now for a Smooth Transition

🎯 Essential Points to Remember

Migration to Windows 11 is no longer an option, but a strategic necessity to ensure security and sustainability of your digital environment. Microsoft has drawn a clear line: PCs must meet modern security standards (TPM 2.0, Secure Boot) and performance (8th gen processors minimum).

The good news? For the majority of users (64%), compatibility is just a BIOS configuration issue. A few minutes are enough to enable TPM and Secure Boot, unlocking access to Windows 11 without any financial investment.

🚀 Your 4-Step Action Plan

🔍

Step 1: Diagnosis

Use PC Health Check to precisely identify your PC's blocking points

💾

Step 2: Backup

Create system image and copy important files (OneDrive, external drive)

🔧

Step 3: Corrections

Enable TPM and Secure Boot in BIOS, or plan necessary hardware upgrades

Step 4: Migration

Proceed with installation before October 2025 via Windows Update or clean install

⏰ The Urgency of the Situation

October 14, 2025 is not a trivial date. From this day, every PC running Windows 10 becomes a priority target for cybercriminals. Ransomware, zero-day exploits, and malware will primarily target unpatched systems.

Alarming statistic: According to CERT-FR, unupdated systems suffer +340% successful attacks in the year following end of support. Don't let your PC become a gateway for cyberattacks.

🌟 Windows 11 Benefits

Beyond security, Windows 11 brings concrete improvements:

Feature Benefit Impact
DirectStorage Optimized game loading Up to 75% faster
Auto HDR Automatic visual enhancement 1200+ compatible games
Modernized interface Snap Layouts and virtual desktops Improved productivity
CPU/GPU optimizations Enhanced gaming performance +10-15% on recent architectures
Long-term support Guaranteed updates Until 2031 (6 years)

💡 What If Your PC Isn't Compatible?

If your processor is from before 2017 and upgrade is too expensive:

Option Solution Cost Ideal for
Option 1 Migrate to Linux (Ubuntu 24.04, Linux Mint 22) 💰 Free Technical users, office work
Option 2 Refurbished PC compatible with Windows 11 From $300 General public, simplicity
Option 3 ESU (Extended Security Updates) Paid (enterprise) Professionals, additional delay
