Question 10 – Why does PicoZip’s icon look weird in Windows 95 ?
Q: I installed PicoZip in Windows 95 and noticed PicoZip’s icons/shortcuts seem to be “discolored”. How do I fix this ?
A: Windows 95 by default only supports 16 color icons. PicoZip’s icons uses 256 colors, so when it is displayed in Windows 95, it looks rather ugly. You can fix this by making some changes to the Windows registry. Please note that you should NOT do this unless know exactly what you are doing. Here are the steps:
Run “Registry Editor” by selecting “Start -> Run”, then enter “regedit” and click OK.
Go to “HKEY_LOCAL_MACHINE\Config\0001\Display\Settings”.
Look for “BitsPerPixel” and note down the number (probably 16, 24 or 32).
Now, go to “HKEY_USERS\.Default\Control Panel\Desktop\WindowMetrics”.
Add a string value “Shell Icon BPP” and give it the same value you note down in Step 3. Note: If there is no “WindowMetrics” key, just add it, then add the “Shell Icon BPP” string value.
Restart Windows.
