Starting where SPEEDOS left off, for which you'll need the 98Lite Pro software, 25$ from click here, this is a 16 bit system, and that left open to me the prospect of reverting to the pre-registry Microsoft days with the advantages that can hold, many not wholly agreeing with the change to having a registry. Pre-registry computers weren't liberally endowed with drivers but did use more inf files, and in line with that the System 32 folder and all it's driver content has no value. The only exception in my computers are USB2 drivers which are stored elsewhere anyway.
Knowing that you will have a 16 bit system guides you as to your actions with files bearing the 32 in their title, but your action will be different with 3216 files of course. Equally, very large numbers of DLLs will serve no useful purpose, and the version tab reached by right clicking and selecting Properties will help in determining that.
The excellent Cleansys 7 program can identify and shift to another folder a large number of the redundant DLLs, but there's no avoiding doing the job manually afterwards to achieve the best results, while an examination of the INF files in Notepad will reveal those with no relevance to your hardware. Also in the INF folder, you may notice a shadow version of every single INF file, and NONE of those are necessary to the functioning of your system.
Add to that, of necessity very brief guidance, the superb HyperOS program, bringing your total expenditure to about 191 pounds with the 98Lite, and you too can time travel to the future of computing.
Following the experience with SPEEDOS, I really cannot give support or further advice on Strewth!, the workload being too great, but I'm sure that I'm not the only one in here with the imagination and daring to do the impossible. You all have within you the ability to achieve the miraculous, you need only dare to try, ignoring all the fainthearts for complete success to be yours.
