Windows: The "Activate Windows" Watermark
The "KMS Pico" Trap:
Many Nigerian technicians will "crack" your Windows using a tool called KMS Pico.
The Danger: 90% of these activators contain "botnet" malware. They use your laptop's power to mine crypto or attack other computers in the background. This is why your laptop fan is always screaming.
The Solution:
1. Ignore the Watermark: You can use Windows 10/11 forever without activating. You just can't change your wallpaper. It is better than a virus.
2. OEM Keys: You can buy cheap "OEM" keys (₦5k-₦10k) from reputable sites. These are legal grey-market keys from scrapped corporate PCs.

Office 365 vs. WPS vs. Google Docs
Microsoft Office is Expensive:
Paying ₦40k/year for Word/Excel is hard for students and freelancers.
1. WPS Office (The Nigerian Favorite):
Pros: It looks exactly like Word. Opens everything.
Cons: The ADS! Every time you save, it tries to sell you premium.
2. Google Docs/Sheets (The Professional Choice):
Pros: Free. Autosaves to the cloud (never lose work to NEPA again). Real-time collaboration.
Cons: Needs internet to start (but can work offline if set up).
3. LibreOffice:
The open-source hero. Totally free, no ads, but the interface looks like it is from 2005.

PDFs: Stop Paying for Acrobat
The Scenario:
You need to merge two PDFs, sign a contract, or convert Word to PDF. Adobe wants a monthly subscription.
Free Tools:
- iLovePDF.com: The holy grail. Merge, Split, Compress, Sign. All free.
- Microsoft Edge: Surprisingly, Edge is the best free PDF reader. You can draw, highlight, and read aloud.
- Google Drive: Upload a PDF, right-click > "Open with Google Docs". It converts the PDF text to editable text. Magic.

Antivirus: Why SmadAV is Not Enough
The USB Virus Era:
SmadAV was great in 2010 for shortcut viruses on flash drives. In 2026, it is useless against ransomware and modern trojans.
Windows Defender (Security):
It comes free with Windows. It is now one of the best antiviruses in the world.
Rule: You do NOT need a 3rd party antivirus (Avast, Norton) if you keep Windows updated. They just slow down your PC.
Malwarebytes:
Keep the free version installed. Run a scan once a month to catch "Adware" (annoying browser popups) that Defender might miss.

Zoom vs. Teams: Saving Your Data
The Data Consumption Leaderboard (1 Hour Call):
1. Zoom (HD): ~1.5GB. (Data Hog)
2. Microsoft Teams: ~1.2GB. (Heavy)
3. Google Meet: ~800MB. (Efficient)
4. WhatsApp Video: ~300MB. (Potato Quality but cheap)
Optimization Tip:
Turn off your video if you are just listening. It reduces data usage by 90%. Use a virtual background to hide your unmade bed, but be aware it uses more CPU (battery).
