If Windows is getting slower and slower, it may be busy swapping to the slower hard drive because the PC doesn’t have enough fast RAM. Windows stores everything that no longer fits in the fast main memory on the hard drive.
Uninstall old programs
To eliminate the slowness of Windows in such a case, it helps to increase the storage capacity again. For this purpose, you should first clear up the memory and check whether programs are installed that you no longer need and that can actually be uninstalled.
To do this, click on Start, then on Control Panel, and look at the installed programs under Programs/Software. If you consistently rid yourself of the programs you don’t need, you’ve already gained new memory.
Disk defragmentation
Defragmenting the hard drive by rearranging and sorting the data also helps. This also helps that working with Windows – and thus swapping out the main memory – is accelerated again.
Buy new memory
You should only think about buying new RAM if this clean-up doesn’t help. For this purpose, it is advisable to have the RAM installed in the computer directly by the dealer, since there are many types of memory components and these must fit the respective computer.
